"Having said that I believe they were managing to detect periscopes and snorkels which is tricky even with 1970s era radars"

I may be remembering quite wrong, but wasn't there something about the apparent noise of early radar sets actually picking up the (fairly long distance) wave patterns of periscopes and snorkels, something that was then forgotten in the race to ever shorter wavelengths?

Certainly the Soviet Union was said to be using quite primitive long wave radar to detect nuclear subs by the surface patterns from their props (interference).
