"- how was the target originally acquired? (Height-finder RADARS aren't used in search mode - but *may* be used to determine a target's height once detected on (or appearing on) the primary *search* RADAR ... "

PAR or Pulse Acquisition Radar (Constantly Rotating) is used to acquire targets at altitudes from roughly 15,000 to 90,000 feet.

"See, a horizontal scanning (rotating) "search" RADAR won't paint/detect overhead targets - and this is assuming that 50's destroyers were equipped with height-finder RADARs ..."

CWAR Constant Wave Acquisition Radar detects from about 22,000 to just above ground level for low flyers.

Can you give me an AN/XX number on that particular RADAR, cause, I think you just laid out a line of BS.

See, they (Search RADARS and even Height-finders) all work on the principle of 'pulses' emitted at microwave frequencies, so, you have not enlighted anybody here, but, you are potentially embarrasing yourself ... bigtime ...

Is your pespective set to the 1950's shipboard RADAR? (I don't think it is, and that's what we're discussing here. Technology has come a long way since the fifties ...)

CW RADARs are unsurpassed in terms of cost for their applications, but, those applications are limited ... that's why there is a host of other RADARS and for particular applications ...
