A radar device is provided with a pulse modulator (203) for generating a pulse signal, a transmitter (101) for generating a transmission signal from the pulse signal, an antenna element (102) for emitting the transmission signal into the air, a plurality of antenna elements (204) for receiving reception signals reflected by a target, phase shifters (205) for converting the received reception signals into signals having mutually different wavelengths, an adder (206) for adding the converted reception signals and generating a reception video signal, an A/D converter (208) for carrying out A/D conversion on the added reception video signal, a frequency range conversion unit (301) for converting the A/D converted reception video signal into frequency ranges, a target candidate detection unit (302) for detecting a target candidate from the signal power of the converted reception video signal, and a target candidate direction calculation unit (303) for calculating the direction of the target candidate from the detection results. |
