There are also a couple K band POP units, not sure who makes them. It is the most common POP radar. It consists of a lightning-quick radar burst, over and done with before a radar detector can pick up the signal. The bursts are supposed to be long enough though to detect the vehicle’s speed. Bee which operates on 33.8 Ghz Ka and has the POP feature. A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun.Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.In general sense, only emitting technologies, like doppler RADAR, or LIDAR can be detected. To detector POP radar, radar detectors have to enabled to detect it and not all detectors have the ability to do so. POP radar’s main use is to defeat the use of radar detectors. I believe the Valentine One is the only detector that will detect both Ka POP and one type of K POP. Intelligent and high performing, the Escort iX offers some of the longest potential range on a radar detector across the X, K, KA and POP frequencies. “POP” radar is a speed detector which broadcasts its radar signal for an extremely short time so as to be very hard for a radar detector to pick up while it scans the different radar frequencies. The idea is that the short bursts won’t be long enough to trigger the radar detector.
A major indication of the effectiveness of POP technology is the variety of “hate” websites devoted to it by radar detector companies such as Valentine (manufacturer of the “best” radar detector on the market). Buoyed by its superior sensitivity, the maximum range coverage is a real boost for drivers who are constantly on the road, especially on long stretches of highway where advanced detection can make all the difference. The radar works by sending out very short bursts of radar. In response to this, police started using POP. The POP mode is fundamentally flawed. The M.P.H. Furthermore, when POP radar detection is enabled on most detectors, they tend to false more and their detection range of conventional I/O radar tends to drop. Escort/Beltronics detectors that have POP detection will only detect Ka POP. We consistently measured the POP duration at 67 milliseconds (that’s 0.067 second). Most radar detectors cannot detect the POP mode signal, although sometimes one gets lucky.
