To the contrary, were it a radar it would be very, very efficient since it would be a pencil thin beam striking mainly the targets they are looking for with no side lobes. Also, if you use cognitive radio technologies you would not expect to see this blip on the same frequency for a long time.
Also if the signal originated from a pulsar spinning stupendously fast we would see a pulse train and a distinct power distribution curve very different from what is shown here. And even radio amateurs using cheap equipment can detect pulsars. If the beam hits you once it will hit you again simply because the gyroscopic effect of a huge mass rotating thousands of RPMs would be too enormous to precess quickly.
