FM-CW RADAR PROCESSING DEVICE

摘要

An Fm-CW radar processing device pairs the peaks which are acquired by fast Fourier transform of the beat signals associated with an up-section and a down-section of a triangular wave of an FM-CW wave, calculates the distance to or relative velocity of a target from the peak frequencies of the up-and down-sections acquired by the pairing, and compares the distances or relative velocities acquired before and after the switching of the modulated signal of the FM-CW wave. The pairing is judges to be a mispairing if the distances or relative velocities before and after the switching of the modulated signal are different.
