If your detector is beep, beep, beep beeping, your reading the pluse of the doppler effect. Its the stream of signals being transmitted. Doppler operates on multiple bands, like X, K, KA.

The further away you are, the more spread out the pulses are, same as your beeps. Fast beeps, close.

The doppler measures the difference in the reflection and transmission. Think of shooting a machine gun, the trigger is pulled but a bullet only fires a fraction of the time the trigger is actually pulled.

A doppler radar can be "on" and you won't know it. Not until the trigger is pulled does it transmit. Let me tell you, its quick, real quick. Like I posted before, some detectors fail to read it.

Angle, greater the angle, less your speed. Errors on your side.

Of course if the officer is hitting a car up in front of you, you'll get a faint/slow beep or "early warning." When your the target, forget it, your nabbed.
