Kind Code:
A1
Abstract:
Provided is a radar system (1) having a receiver array antenna (20), wherein a signal processing device (30) comprises: a receiver unit (21) which mixes a plurality of received signals and some transmission signals and generates a plurality of beat signals; a domain converter unit (31) which converts the plurality of beat signals into a plurality of frequency domain signals; an all-domain search unit (32) which calculates a first integrated signal by integrating the plurality of frequency domain signals, and detects first target information (Di) on the basis of the first integrated signal; a limited-domain search unit (33) which generates a plurality of phase shift signals by shifting the phases of the plurality of frequency domain signals in order to limit the target detection area to a specified direction of the domain, calculates a second integrated signal by integrating the plurality of phase shift signals, and detects second target information (Dj) on the basis of the second integration signal; and an information output unit (34) which outputs at least one of the first target information (Di) and the second target information (Dj).
