The receivers just aren’t that delicate, and by the time you’re in range to try something fancy and expensive you’re also in range to just throw something that explodes at the radar. Believe it or not explosives are insanely inexpensive for governments, especially compared to a death laser like you’re envisioning.
Not to mention your death laser is also throwing out huge amounts of the same radio waves that could lead a radiation tracking missile right up your nose.

If there only was a way of throwing something fancy and expensive that explodes and defeats the radar via electronic effects at it from very far away.
Oh wait, there is. Just nuke the ionosphere somewhere above the vicinity of the radar and have the resulting EMP take it out.
