Abstract:
1. An object detecting apparatus, comprising: a transceiver that transmits FM/CW waves toward a plurality of detection areas and receives a reflected wave of the transmitted FM/CW wave from an object; a frequency analyzer that generates a beat signal from the transmitted wave and the received wave of the transceiver and subjects the beat signal to frequency analysis; a peak signal detector that determines peak signals on the rising side and the falling side based on the results of the frequency analysis by the frequency analyzer; and an object candidate information storage device that stores as object candidate information a distance or a relative speed for an object determined based on a combination of peak signals on the rising side and the falling side of each detection area, wherein, when the difference in frequency between peak signal group the two peak signals, and calculate the distance or relative speed of the object based on a combination of peak signals on the rising side and the falling side after the grouping processing.
