I do not know if the tracking
radar and cop's radar gun were on the same band, however I do
know that
1MW of microwaves was sufficiently nondiscriminatory at the
receiving
end to burn out its front end.

I bet it was sufficiently nondiscriminatory at the receiving
end to burn out the cop's front end, too.

When people talk about megawatt radars, they are talking pulse
peak powers.
Radar pulses are very narrow - less than a microsecond. However,
its peak voltage that usually frys semiconductors.

If these megawatt-rated radars were not sending out short
pulses, but continuous power, they'd have to build a commerical
electrical generating plant next to them to run them in the
field.

Nike HIPAR, 10.4 MW, pulse width 6 microseconds.

10.4 * 10**6 * 6 * 10**-6 = 62.4 watts average power.

Hawk 2nd generation tracking HPIR CW RADAR AN/MPQ 39 power seems
to have
not yet been revealed publicly. It has been publicly stated that
the AN/MPQ 39 power output level exceeded that of the earlier
AN/MPQ 33, which was 125
watts. This is a vast understatement!

AN/SPG-51 and AN/SPG-53 tracking / target illumination radars
were/are rated at 22.5 kW continuous and 35 kW continuous. They
were real good at knocking birds out of the sky.
