Will LPI radar be used to guide SAMs?

This NG loves to talk about whether or not stealth aircraft can be
detected. What about the issue of detecting SAM radar? If LPI, or Quiet
Radar techniques are used on the ground radars guiding SAMs this will
make it difficult to find and destroy the radars.

The problem with LPI is that most of them are just very low power,
continuous-wave radars with a huge chunk of signal processing gear
tacked on. Smaller output, harder detection, right?

Except that defensive measures are getting better, too, for the same
reasons, and with that low power, jamming becomes much easier. And if
you get the power low enough, a cheap, disposable white-noise jammer
takes the whole thing out of the equation (most LPI sets are pretty
darned close to the noise threshold to begin with, which is what makes
them hard to detect).

Even with frequency hopping or broadband techniques, you're still
broadcasting a signal of *some* sort, and the smarter ECM systems will
still find you.
