Grüß Gott,danke für Ihren Militärdienst. Entschuldigen Sie mich bitte, aber mein Deutsch ist schrecklich! :doh:
Then you're knowledge of airborne fire control radars is inadequate to this discussion. :smartass:
Modern fighter targeting radars as well as SAM radars are pulse dopper variety & not continuous wave, which are more easily vulnerable to ECM. All that's required to target a semi-active radar homing missile is HPRF. Active radar missiles also use HPRF for terminal guidance to their target, once it's acquired.
I didn't forget this, as it's blatantly obvious. You must not know that this is irrelevant to FCRs of modern aircraft and SAM systems. The fact that the blades are in motion cause enough of a radar return that we usually get a velocity readout on the blades, which settles down as the target is sorted. We know the target is a helo when the velocity doesn't match it's groundspeed - initially.
So, with your background, if it's recent, I would've thought you'd be more familiar with modern airborne and SAM radars. Perhaps you were in the navy during WW2? :doh: Sitting stationary on the ground is, in general, a good way not to be detected by a modern pulse doppler equipped fighter. However, it's not so good while you're trying to beat the air into submission with your rotor blades, regardless of whether you're stationary - on the ground or hovering. Once we notice you, the only way we will lose you is if you terrain mask, or land and spin down the rotors.
I don't think you're comprehending what you read. Either way, it was Bakke, Bennett's WSO who picked up the Hinds at 50NM as they were moving. The Hinds were moving, stopping to drop troops off, then moving again, all the while lock was maintained. As they got within weapons employment distance, they switched command of the radar from the WSO to the pilot - as mudhen crews are trained - and Bennett maintained lock as Bakke lazed the target. Bennett later says the following in the article YOU quote: "The radar would stay locked on them when they were on the ground because the moving rotor blades were picked up."
Completely incorrect for a modern pulse-doppler equipped fighter. As I've said before, on my B-scope, I have a solid return - none of this "blurred" contact stuff you report. However, I also have a velocity readout on that stationary target that is initially high, then settles down. This is a clear indicator - at least to me & my training, that I've locked up a helicopter. You don't seem to realize that we've modernized our equipment since you apparently were in the navy.
