Traffic radar system with multiple zone target detection

A traffic radar system comprising:

• a first radar transceiver assembly configured to transmit and receive radar beams from a front zone corresponding to an area in front of a patrol vehicle and to generate a first electronic signal corresponding to the received radar beam;
• a second radar transceiver assembly configured to transmit and receive radar beams from a rear zone corresponding to an area behind the patrol vehicle and to generate a second electronic signal corresponding to the received radar beam;
• a display configured to display a plurality of speeds, each speed being a speed of a target vehicle;
• an analog to digital converter configured to receive the first electronic signal and the second electronic signal and output a plurality of front radar digital data samples and a plurality of rear radar digital samples;
• and
• a processing element configured to
• receive the front radar digital data samples and the rear radar digital data samples,
• perform a time domain to frequency domain conversion on the front radar digital data samples to determine speeds of at least one target vehicles in the front zone,
• perform a time domain to frequency domain conversion on the rear radar digital data samples to determine speeds of at least one target vehicles in the rear zone,
• control the display to display the speeds of the target vehicles in the front zone or the target vehicles in the rear zone based on predetermined parameters, and
• control the display to display a first speed of the target vehicle with the fastest speed and a second speed of the target vehicle whose reflected radar beam had the greatest magnitude.

A computer-implemented method for displaying speeds of target vehicles, the method comprising:

• buffering a plurality of front radar digital data samples;
• processing the front radar digital data samples to determine speeds of at least one target vehicles in a front zone corresponding to an area in front of a patrol vehicle;
• buffering a plurality of rear radar digital data samples;
• processing the rear radar digital data samples to determine speeds of at least one target vehicles in a rear zone corresponding to an area behind the patrol vehicle;
• comparing the speeds of the target vehicles in the front zone with the speeds of the target vehicles in the rear zone;
• displaying the speeds of the target vehicles in the front zone or the target vehicles in the rear zone based on predetermined parameters;
• and
• displaying a first speed of the target vehicle with the fastest speed and a second speed of the target vehicle whose reflected radar beam had the greatest magnitude.
