I came up with an idea that, if implemented by the RD manufacturers, could possibly reduce or eliminate POP falses.
Since most POP falses are caused by the LO sweep emissions in certain detectors, and this sweep repeats several times per second, what do the experts here think of an algorithm similar to this to weed out Cobras from BEE IIIs:
1. When a POP burst is detected, instead of alerting immediately, wait for a period of time (<1 second) to see if the burst repeats.
2. If it repeats within the time period, do not alert. If it doesn't repeat, then alert.
About the only drawback is a slight delay in alerting to POP bursts, but if you're POPped and you're the front runner, you're dead anyway. With enough sensitivity, this would allow the detector to pick up POP bursts when other cars are clocked up ahead. Also, the detector could still false if it only picks up one LO sweep from a junk detector. But I figure this would reduce the occurrence of falses quite a bit.
Another possible drawback, if implemented, is MPH adding a multiple POP burst that emulates a Cobra, causing the detector not to alert.
VR has a method for detecting POP falses, but it's not perfect. Worse yet, it sometimes junks out real Ka threats (that aren't even POP at all).
Any thoughts from the peanut gallery?
