This is not true, in several ways:
(1) The amount of power necessary to fry radar front ends is measured
in Watts peak. At these levels, the microwave beam is innocuous
unless you spend a lot of time in it.
(2) Police radars use neither high peak power nor low duty factor.
I used to work on an aircraft with 160 kW peak X-band radar. While
I wouldn't recommend standing in the beam at 3 feet (which inadvertently
happened to me once), you are relatively safe at 1000 feet. However,
we used to fry radar receiver front ends at 2500 feet of range (by
accident - we didn't realize that the nice reflector we would tune
up the radar on was the GCA site, and contained radar receivers.
