False signals can come from other devices such as the
automac doors at a supermarket or even another
car’s cruise control; these devices operate in the
same frequency ranges as radar guns.
BANDS

POP™ is a single-pulse Doppler radar feature on some
K and Ka band radar guns. This type of radar gun is
a very sensive receiver; limit POP detect mode to
highway and rural driving.
