이진 분류기법을 이용한 24 GHz 실외용 도플러 레이더 모듈

Abstract

24GHz doppler radar module has been fabricated for low-cost and an algorithm which can be used for the energy saving of outdoor lamps has been proposed. The proposed algorithm can differentiate targets such as pedestrians, moving bicycles and vehicles from false alarms caused by environments. By increasing SNR, detection range for targets can be increased and applied to outdoor power-saving motion sensors. In order to verify that false alarm rate by the external environment is small enough, false alarm rate has been tested against swaying trees by wind and flying insects nearby the radar. The detection range for the pedestrian has been found to be more than 30m.
