On-vehicle radar device and target target detection method applied to on-vehicle radar device

摘要

PROBLEM TO BE SOLVED: To reduce the probability of occurrence of interference and detect a target with high accuracy, and to reduce power consumption.SOLUTION: The present invention comprises: a transmission antenna (103); a plurality of reception antennas (104); a signal processing unit (108) for generating a beat signal corresponding to a received signal and applying signal processing to the generated signal to detect a target; a target of interest detection unit (109) for detecting a target of interest on the basis of the result of detection by the signal processing unit; a target of interest detection state determination unit (110) for determining whether a detection state of the target of interest satisfies a predetermined determination condition; and a control unit (101) for selecting, when the detection state of the target of interest satisfies the determination condition, a transmission signal for stopping transmission from among a plurality of transmission signals, and controlling transmission/reception processing by the transmission antenna and reception antenna and signal processing by the signal processing unit according to the selected transmission signal.
