ABSTRACT:
Systems and methods for measuring the speed and/or direction of a target such as a vehicle in a field of view. The speed of a vehicle is measured using distance measurements, phase measurements, or Doppler shift measurements using a single transducer side fire configured sensor. The speed of a vehicle can be measured using laterally spaced transducers in a side fire or off angle configuration and using a single transducer sensor in a forward fire configuration.
