Known as passive radars, they are reported to be able to locate all types of aircraft - including stealth aircraft - while themselves remaining virtually undetectable.

Passive radars are not vulnerable to HARM missile attack, since they do not emit any signal. They monitor existing VHF/UHF TV transmissions and cell-phone tower transmissions. A stealth aircraft may absorb radar directed towards it, but it will cast a "shadow" if it flies between a TV tower and a passive radar station

If you target the electrical power generating and distribution systems, there won't be enough power available to run cell phone towers and TV stations.

All one has to do is target the towers, which I think HARM can do. If they're using cell towers, while they're much harder to target (more of them, and they're usually piggybacked onto a civilian target), the range is less simply because the signal used is weaker.

Simple solution, remove the transmitter part of the
system. Bye bye TV tower, cell phone tower, and all other emitters with enough signal strength to be used
by the detection system.

"Passive" really isn't correct, since there is an active
transmitter involved, just at a remote location from the receiver.

And there are just so many TV and radio towers
spread strategically throughout Iraq.

which will suffice to inform Abdul that he'd better duck, fast... but not in sufficient time to allow him to do so, much less *track* the object that just blew him to Allah...
