The plus effect is that a direct vision cathode ray tube (actual radar
blips on the scope) adds about 3 db to the radar's effectiveness
because the human eye/mind integrates the information and can discern
targets below the noise peaks - because noise is random and the radar
blis are not. It takes some experience but it definitely works.
So a 60's type radar would still be fairly effective aginst aircraft
out of the sea return, effective enough for fire control purposes.
Against the extremely low altitude target - when the CV Eisenhower was
working up the PRANG A7s could get at it by such an approach.

Even with today's modern radar you need to be on the ball. Set the radar up
wrong and you'll be getting holes punched all over you. Some guys who worked
the system could really set up things well
