And, yes, I know about LPI radars. But the one thing about a long-range radar is that it has to radiate power, and one side can detect the other's transmitter long before they themselves are detected. Now add space elint to the equation, GPS/Inertial guided missiles with ecm terminal homing and blithely boring holes with the radar on will quickly go out of fashion. Even more so, radar ground sites in known/easily pin-pointed stations. Boats, too, for that matter. Might as well have a huge neon sign saying "Hit me". Even in 1960 we had missiles that could switch to ecm home; not much of a step to homing on AI radar with our progress in micro processors. Now bring in satellite elint and direction . . . Walt BJ Even in 1960 we had ecm systems that would listen to check if a missile had switched to ecm home.G And it would know that _how_? The missiles in question don't emit anything, they just look for a source of RF in front of them. That source can be (In the simplest case, a CW SARH like a Sparrow III) the reflection of the illuminator's beam, or the jillion times more brilliant source of teh target's jammer. The missile really would prefer to have the Illuminator doing the job - it compares thw signal from behind (The illuminator directly) with the reflected signal to get closure rate inforamtion - but it's also quite happy tp get its Az-El data from the jammer, and trust its Prox Fuze to do the job. The shooter gets a much better picture (minus range data) of teh target's Az-El, with the much brighter signal coming from the jammer. (Of course, you'd have to dial the receiver gain down a bit, bit that doesn't show) So it's not too tough to keep teh target in the illuminator's beam, which reveals nothing wrt jammer effects. (Dang, if I'm not careful, I'll start sounding like Kurt Plummer!) In any case, there's no different behavior from wither the missile or the shooter that would give anything away. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |
