Radar system for detecting distance, mutual speed and azimuth of a target obstacle

摘要

Receivers (14) and (16) comprise mixers (14b) and (16b) for mixing reception signals of receiver antennas (14a) and (16a) with a transmission signal to generate beat signals B1 and B2, respectively. Signal processing section (20) performs the Fourier transformation of beat signals B1 and B2 supplied from receivers (14) and (16) to obtain the phases of beat signals B1 and B2 and then obtain the azimuth based on the difference of these phases.
