Abstract
An object detection apparatusincludes: a transmission unit, having a transmission antenna, configured to emit a radio wave toward an object using the transmission antenna; a reception unit, having a reception antenna, configured to receive the radio wave reflected by the object as a reception signal and generate an intermediate frequency signal from the reception signal received; and a processing device. The processing devicecalculates an amplitude distribution of the radio wave reflected by the object on the basis of the placement of the transmission antenna, the placement of the reception antenna, the frequency of the radio wave emitted from the transmission antenna, and the intermediate frequency signal, and furthermore, using a correction operator calculated from a point spread function indicating characteristics of the transmission unitand the reception unit, corrects the amplitude distribution calculated.
