摘要: A vehicle radar device provided with a transmission and reception unit for generating a beat signal from a transmission signal and a reception signal, a frequency analysis unit for generating a two-dimensional spectrum including a speed component and a distance component by applying prescribed frequency analysis processing to a signal sequence of the beat signal, and a speed determination unit for dividing the speed component of the two-dimensional spectrum into a plurality of blocks, carrying out constant false alarm rate (CFAR) processing on each of the plurality of blocks, and specifying the speed of the vehicle of the radar device on the basis of a threshold obtained through the CFAR processing.
