Abstract

Provided is a radar device including: a transmission circuit that transmits a first transmission signal and a second transmission signal which have frequencies different from each other; a reception circuit that receives the first transmission signal and the second transmission signal which are reflected by one or a plurality of objects as a first reception signal and a second reception signal, a processor, and a memory that stores a command group executable by the processor. Quadrature demodulation is performed with respect to each of the first reception signal and the second reception signal, at least one of the first reception signal and the second reception signal is rotated on an IQ plane in correspondence with a predetermined phase angle corresponding to a predetermined distance, and the first frequency or the second frequency, the first reception signal and the second reception signal of which one is rotated is added or subtracted, and the one or plurality of objects are detected on the basis of a processing result of a processing means.
