Radart Guns, K & Ka Band Radar Gun Receiver Sensitivity

[SueSmith]

Does anyone know how much power, in watts, it would take to blow out the receiving unit of a radar gun, rendering it inoperable?

Strictly speaking of the power of the transmitter doesn't make much sense, you'd want to know the specific power (i.e. intensity, W*m^-2) delivered to the remote unit...

I'd personally doubt overloading the receiver in terms of signal strength to blow out digital radar guns these days, you'd probably want something in the terms of an EMP. There are several experimental EMP devices that emit on the order of 10-20kW focused with a crude antenna that's able to disable microprocessors just by overinducing current.

Such devices are not exactly compact, safe, or legal though

And the electronics which you fry could be your own!
