Timing Animation

Microwave and laser police radar minimum time to acquire, establish, and track a target varies with model from about a quarter of a second (250 milliseconds = 250 ms) to a half of a second (500 ms) or more. In many (most) cases a radar may (will) require more than 1 sample time period (integration time period) to establish speed.

Time Period
Sample Rate
250 ms 4 per second
300 ms 3.3 per second
333 ms 3 per second
500 ms 2 per second
750 ms 1.25 per second
1000 ms 1 per second
