Title: RADAR DEVICE
Abstract:
This radar device (1) is provided with: a signal isolation unit (31) which isolates, from a plurality of digital reception signals, a first digital reception signal consisting of a sequence of odd-numbered sample values and a second digital reception signal consisting of a sequence of even-numbered sample values; a complex multiplication unit (32) which generates a plurality of multiplication signals by multiplying a complex conjugate of one of the first digital reception signal or the second digital reception signal by the other of the first digital reception signal and the second digital reception signal for each of the plurality of time intervals; a domain conversion unit (34) which converts the respective multiplication signals into a plurality of frequency domain signals; and a signal synthesis unit (36) which generates a synthesized signal by integrating the plurality of frequency domain signals.
