Patent attributes
A radar device mounted in a moving object includes a radar transmitter and a radar receiver. The radar receiver includes a plurality of antenna brunch processors that perform correlation processing of the received returning signals and the radar transmission signal, and generate respective correlation signals each including arrival delay information of each of the received returning signals, an electric power profile generator that generates an electric power profiles for each arrival direction of the received returning signals and Doppler frequency component, using the generated correlation signals, and a stationary object group distribution generator that, based on the generated electric power profiles, obtains a first distribution of a Doppler frequency components of a stationary object group including a plurality of stationary objects as the plurality of targets in the perimeter of the moving object, for each azimuth angle.
