Evaluation of Target Detection Performance for UWB Vehicle Radar at 24GHz

摘要

Vehicle radar receives echoes from the natural environment such as road and building. These echoes are called clutter which can be much higher than vehicle echo. It is therefore expect to improve the detection performance by summing all the radar echoes available from the vehicle. However, heavy road clutter should not be suppressed less than the vehicle echo. Also the radar echo should include multiple vehicle targets as well as the clutter. Therefore it is not easy to detect multiple vehicle targets from heavy road clutter. In this paper, target detection with new clutter suppression scheme is discussed and the usefulness is investigated by conducting the measurement. As a result, by the suggested scheme is found to suppress the heavy clutter significantly and improve false alarm rate.
