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
Okay so I was overly general with my first statement.
No one is saying passive radar systems don’t exist. We’ve been using them for decades and there have been massive improvements. But the actual radar system we’re discussing here isn’t. You simply aren’t going to get the same capabilities from a purely passive system than you will from an active + passive system where you can tightly control the frequencies and directions you are transmitting on, and have the information about what frequencies you transmitted on, when you transmitted them, and how (what array configuration) you transmitted them. The point is that the transmission itself is structured to reveal certain information. So when you get a response back (also, coming back to a phased system), you can learn far more about your target than you could in a purely passive system because you that prior information about what you transmitted.
