Mystery Israeli satellite telly disruption blamed on UN Mysterious high-powered transmissions have caused a month of severe interference with Israeli satellite television, threatening the commercial viability of the country's major sat-broadcaster. The signals - source thus far unknown - are not thought to be connected to any Independence Day-style pre-invasion alien …
I would be surprised to know that the same type of technology used to cancel noise electronically found increasingly in everyday items like headphones is being employed. The aircraft only need a radar detector to pick up the rader signals emitted from the ground and send back a radar signal that effectively cancels or reduces the reflected waves so as to not be detectable or can not be interpretted by the software in the radar systems on the ground.
Afterall we are only dealing with electromagnetic emmissions and reflections, its not exactly rocket science IMO!
"the naughty radar is specifically an "army radar", not a naval one - unless that's a translation error"
The most likely explanation is that the Israelis don't have a navy as we would understand the term. All three branches of their military are distinct, but they all fall under the aegis of a single command structure with a primary emphasis on ground forces. The whole lot could conceivably be called "the Army", which makes it likely that a spokesman would make the minor slip of assigning their own understanding of military terms to foreign military equipment and organisation. *shrug*
"Even if it is only sat TV being disrupted at least the Issies are getting some sort of grief."
Yes, because daily terrorist attacks from Hamas and other Syrian and Iranian funded terrorist groups aren't grief enough or anything.
Oh nevermind, I forgot that people seem to think it's okay for Israel to suffer daily terrorist attacks, but when they do something back it's suddenly time to call for uproar because god forbid jews ever be allowed to fight back and defend themselves, only the poor poor muslims are allowed to do that.
If only people like you had to live close to the Gaza strip or Lebanese border, perhaps then you'd actually understand the situation rather than ramble on about something you blatantly have no clue about.
"Oh nevermind, I forgot that people seem to think it's okay for Israel to suffer daily terrorist attacks, but when they do something back it's suddenly time to call for uproar because god forbid jews ever be allowed to fight back and defend themselves, only the poor poor muslims are allowed to do that."
Hear that? That's the world's smallest violin playing!
If the situations are comparable, then why not swap weapons? Give Gaza your F15s, armoured personell carriers, missiles and Abramas tanks and 3 billion a year in weaponry, and they'll give you their handguns and suicide bomb belts and 'missiles' capable of punching small holes in breeze block.
Better still why not swap water supplies. You give them the 80% of *their* water you take for irrigation on your land, and they give you the 20% of *their* water they get to keep for irrigation.
I'll tell you what, how about trading freedom of speech, you give them your right to express yourself, through all your US lobbyists and fake front organisations, and you get to be called terrorist and not allowed to be interviewed directly .
You can even trade your television for theirs. I'm sorry to hear your telly is suffering interference, it must be the noise from my violin.
Come back to me when you're happy to trade places, until then it's just Israel whining about situations it created.
If it's a dutch ship causing it, it's likely the goalkeeper system, which is broadcasting in the Ku band, and also very likely, is 'shining it's light' over the coast. Still, how that can ever get over the horizon is a mystery to me..
Still, if commercial stations in Israel are anything like those here, i'd say that it should be seen as a form of 'terror prevention'.
"Oh nevermind, I forgot that people seem to think it's okay for Israel to suffer daily terrorist attacks, but when they do something back it's suddenly time to call for uproar because god forbid jews ever be allowed to fight back and defend themselves, only the poor poor muslims are allowed to do that."
You see what you did there? You started out with "Israel" and then smoothly moved into talking about "Jews". Israelis ALWAYS try and do this, and it just won't wash - Israel will not be allowed to terrorise and murder for ever under the cloak of Jewish religious freedom. Israel is an aggressor, an illegal occupier and its armed forces are guilty of a multitude of war crimes.
We don't hate Jews and love muslims, we hate the aggressive, racist Israeli state, just as we hate the oppressive, dogmatic Iranian and Syrian states.
I think noise cancellation works by taking a sample of the ambient noise and then create an inverse of it and add that to the desired sound (lets say the music in the case of headphones) , so you get the music with a sound which should dampen the ambient noise. To use this as a defence on radar you need to sample the receiving signal of the radar, so it's unlikely.
However I do now that radar do filter a lot of *noise*, like flocks of birds, etc. If you know enough about the software for the radar system you may be able to shape a signal and send that back so the software on the radar filters you out (not that I know of a lot of flocks that can roam around at 600MPH, but you get the idea).
A strange piece of journalism.
Starts with a fact, viz, TV reception problem. Ends with a fact, viz, culprit identified. Yet most of the verbiage wodged in between is devoted to off-topic speculation - and speculation of a decidedly islamophobic thrust.
On reflection, not so strange, perhaps. Well done, my boy, you will go far in this trade.
It seems unlikey that a ship-borne tracking radar or surveillance radar would have sufficient power, spread over enough area to affect so many satellite TV subscribers. Bear in mind that satellite dishes are highly directional and (unsurprisingly) point skywards towards the satellite of choice.
Of course, someone could be jamming the relevant uplinks to the relevant satellites (Amos1&2). That could be difficult to pinpoint and even more difficult to stop if the source happens to be in a non-friendly country.
I was just downstairs watching TV and noticed - again - that whenever certain types of car stop in front of the house the digital signal gets completely bolloxed until the traffic lights change and they move off again. I've seen this happen ever since the digital sky was installed.
What that tells me is that it's entirely possible for signal wash from a radar or other powerful transmitter to blank out satellite signals entirely by accident. The possibility that it's caused by the UN forces in the area - as was the case with the germans previously - seems to be increased a great deal with this knoledge. At least in my mind.
Now as for you lot arguing over Israel's right to defend itself; You try living in a country that suffered daily rocket attacks for over two years without blinking, only to be vilified when it finally decided to sort out the problem. Get over yourselves. Seriously.
This is an interesting subject, and politics notwithstanding, I for one would like to find out more. If only there would be a website focused on technology, that would at least include some technical “bits” once in a while... oh wait... no, that’s not it. I guess such a site cannot exist.
Seriously though, I would disagree with JohnG, uplink jamming seems unlikely, as the satellite operator can easily check the integrity of the feed, as they seem to claim that they have a link with the satellite.
Indeed, why was “fox hunting” (I though this only existed in Soviet Union, now I am pleasantly surprised that other counties played with this too) – or triangulation not attempted by a local amateur radio clubs? Microwave signals tend not to like any obstruction; hence it would be as easy as covering the dish with earthed tinfoil, so that the dish only faces the sky – and then removing pieces of tinfoil to reveal the direction of the interference
Methinks that the most likely explanation is that one or more of the Arabic satellites is using redundant transponders to transmit gibberish on the frequency of Israeli transponders. The signal does not have to be powerful, it would be very difficult to detect, as Arab and Israeli satellites are covering the same region, and, best of all, completely free to the satellite operators. It is even possible that a rouge technician at Arab Sat operations centre is responsible
Having lived in Israel for a period (and no im not jewish or of Jewish decent). My sympathies lie with Israel but not completely - they are responsible for a hell of a lot of bad stuff as well (land grabs, settlers, etc).
But all in all the whole middle east situation comes down to this Israel should never have been set up in the current location. If land should have been taken to set up a jewish state after WW2 it should have been taken from Germany. So my sympathy lies with the Palestinians. But it has now been 60+ years. No Palestinian alive today can remember the land they're trying to claim through the "right of return" as anything but a child's memory. Its time for them to move on and set up proper lives in the West Bank and Gaza. If Israel and Palestine could get on with the future and forget the past both sides would be a hell of a lot better off!
This all comes down to how long does the statute of limitations last, i mean should Australia give back all the land to the Aboriginal tribes that were displaced 200 years ago or the Americans give back all of America to the Indians or should the romans apologise and pay restitution for conquering all of Europe? Where do you draw the line?
Oh and @JohnG - a ship could quite easily cover northern Israel its only a couple of hundred Km's wide!!
Us Aussies worked out a solution to all this decades ago: The Thunderdome. "Two countries enter. One country leaves."
Place a decent chainlink wall around the whole damn region, throw in a container or two of machine guns, chainsaws, kwepie dolls, whatever, then sit back for as long as it takes. Televise it too. I'd watch.
Interesting conundrum , it sounds more like the Israeli's used several methods in combination
Massive broadband frequency interference across the the known Syrian Ground to Air Military Radars
The use of illegal transponders flashing any major airline commercial civil aviation identification codes rather then usual official military IFF codes and then using standard in flight civilian routes flying in from the seaward side
The use of hardware taps into the easily identified heavy duty RF/EMP shielded military land lines which for convenience end up at automated empty civilian telephone exchanges which clued up technicians would have a field day with appropriate equipment attached to the tapping points !
Undoubtedly Israeli intelligence services would have been conducting a long term surveillance of the lines by assorted electronic trickery together with men on the ground prior to the raid and cracked some of the more common general main communication codes in use on these special hardened land lines.
To detect these hard wirings one should run a suite of signal checking programs to search for anomalies and oddities on the lines and send in the manual inspection teams thus or simply check all access cover points on all lines and signal bounce between them , you never know you may get both the tapping equipment and a lead to the agent(s) involved !
If I was a military wanker that is what I would do , plus utilise a number of other long term infiltrated agents as well !
As for the other system hacking problems it is a simple but tedious matter of checking the duty roster for one to seven days day on each side of the event and the system log files for showing who whom and where they were logged on , this will give you insight as to what time the system was really hijacked !
As for station control codes they should really have a general one in use all the time that can be switched to special day/night security alert select rolling one time pad codes activated after a special one time pad run code with the main and secondary command Air Defence Centres to lock out eavesdroppers especially if the main system is designed to shunt non genuine responses to a special dummy set up to mimic the main system thus alerting the command system of intruders !
But hey who cares anyway ! , oops some seems to be breaking down the door , oh no don't tase the computer bro !
Actually, it is rather easy, all you need is a sample of the signal, easy to get as it's beamed right at you, and a knowledge of the scanning speed.
Just have a reciever onboard detect, amplify, and invert the pulse, then delay it until the next one. The result, one initial blip on the radar screen, then nothing.
And yes, I actually have in worked in radar.

If it were that easy, they'd have done it. Don't forget that radar works by sending a signal and then looking for a reflection, if it sees one it KNOWS you're there. So sending out a synthsized signal doesn't blind the system, it makes you visible. It's like arguing that someone with a searchlight couldn't see you at night, provided you shone a torch at them. What you might be able to do is convince the radar you're closer or further than you are by synthesising the "doppler shift". But since you'll be on two sets (at least) at the same time, this is going to be a bit obvious when you stop to think about it. Generally transmitting ANY kind of signal in a modern battle field is a bit unwise, and the moment you turned on your countermeasure you'd show up on any passive system immediately. Don't forget that anything you transmit will be in addition to what is actually reflected from the target and is only likely to appear "correct" to one station.
ECM systems do exist and work, with varying degrees of success. But you're usually better off going for the "unreflective and hidden" appoach than the "blinding them with noise" approach. Hence the design of modern stealth fighters.
The other alternative is to try to talk your problems out like civilised human beings. But where is the fun in that??
You are correct in a way, it is quite simple... that was my initial thought however then I had a reality check.... this is a rapidly moving object we're talking about!
In order to fully cancel the signal you would need to transmit a cancelling signal at around 1/2 wavelength out of phase, as you move there would me a slight shift in this signal phase due to the long wavelengths involved, this would make you generate, from the radar observer's perspective, a weakly modulating intermittant signal.... the frequency of modulation being relative to your speed etc... now granted this might be enough to confuse a current missile system.... but nothing that could not be programmed around... now to fix this you could modify your interferance kit to guess the variations in phase as you move and modulate your output accordingly, reducing the peaks of modulation and making the signal much less interesting, but you're talking about some serious processing power involved here here.... (see the IT angle?)
So you're sat there thinking, ok, its possible.... but why go to all this trouble when all you need to do is focus a high power signal in the general direction of the radar tower, at it's frequency, or in the group of frequencies they might try to use.... you blind the whole radar so it cant see anything, like shining a bright light in someones eyes in a dark room... this is pretty much what radar jamming systems do anyway... and until we start working with phase discriminated radars, regular jamming systems are more effective and cheaper too....
Yes, I agree, any attempt to blind rader just tells the operators that someone is there, SOMEWHERE, doing SOMETHING, and is going to make them look for alternative inputs to descide what and where.... e.g. a mobile radar or on-the-ground look-outs.... or even a radar on a different frequency...
If you want to do a sneak attack, you're much better with stealth... of course if you're doing a full on attack with everything you've got (including non-stealth) any jamming you can throw in is going to cut your losses somewhat...

Any UN ship that switched off its radar would be a sitting duck for an Israeli attack a la USS Liberty. Unlike the Germans, I suspect that the Dutch are not prepared to do so and as a result had a grandstand view of want went on over Syria which Israel would not like in the slightest so they come up with the crap excuse to persuade the Dutch to switch off their radar.
By the way, does any one remember that little war last year in Lebanon when the Hezbollah satellite TV station kept transmitting for most of the time. Were the Israelis able to jam or able to interfere with that? I think not.
The Brits have a fricking great big radar station on top of the Troodos mountains and over-the-horizon radar at RAF Akrotiri in Cyprus, both of which almost certainly also have a grandstand view over Israel, Lebanon and Syria. has any one thought of asking what they saw or were both systems "down for maintenance".
