> And locating radar emissions is a passive process, it doesn’t reveal your own location That depends very much so on the radar system. In practical terms, almost all the radar systems we're discussing here are going to be both transmitter and receiver in one design. You can't simply rely on passive radio energy to detect moving objects in a complex environment. You would want both passive and active beam forming in one instrument; not having both is just leaving some of the most valuable developments in modern radar on the table. And the specific radar we're discussing, is an active, pulsed LFM phased-array radar. It does both, because, obviously it needs to do both. Its wouldn't be useful for its intended use if it *cant* do both.

    Your information about passive radar detection is not up to date. There are tons of passive detection of radar systems that by design do zero emission. The radar array stations will need to emit in order to function, but the enemy can find those radar emitters without emitting any energy of their own https://daronmont.com.au/products/passive-radar
