What does POP detect?

[ryanfx]

Does pop detection just detect very very weak signals of ka that would normally be filtered out? how does it work?

[kpatz]

It detects the very short (67 ms or 16 ms) burst of radar that a gun in POP mode produces.

In the pre-POP days, detectors usually delayed 1/2 second or more before alerting, to reduce falsing.

So it has nothing to do with signal strength, but everything to do with duration and response time.

[ryanfx]

so what exactly does it detect when pop falses oh so often?

Crappy RD's like Cobras.

One of our members up here has an RX65 and never saw a POP false until he drove in the US for a while so definately cheap RD's.
