Abstract
A traffic radar captures the patrol vehicle return signal by saving the patrol return when the radar system is placed in a standby state. If the radar is in standby for more than a predetermined period of time before reentering a transmitting mode, the system searches for a new patrol signal within a speed window around the saved patrol signal speed. If the radar is in standby for less than the predetermined period of time, the system initially searches for a new patrol signal over a range that excludes an interval around the saved patrol signal speed. If the new patrol signal is not found, then in a subsequent search the interval is included in the searched spectrum.
