Abstract
Official abstract text for this publication.
Provided is a radar apparatus that can detect the failure of the transmission switch. The radar apparatus includes: a plurality of transmission antennas; transmission switches that select a transmission antenna for transmitting an electromagnetic wave from among the plurality of transmission antennas; a plurality of reception antennas that receive a reflected wave which is the electromagnetic wave reflected from a target as a reception signal; a signal processing unit that detects the target based on a sampling signal obtained by sampling the reception signal; and a failure judgment unit that compares first reception signals transmitted from one of the plurality of transmission antennas and received by the plurality of reception antennas, with second reception signals transmitted from another of the plurality of transmission antennas and received by the plurality of reception antennas, and judges whether or not any one of the transmission switches has failed based on a comparison result.
