MINIMUM RECEIVING SENSITIVITY CHECK DEVICE OF RADAR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device capable of simultaneously generating many pseudo signals for checking a minimum receiving sensitivity of a radar device in high reliability and in a short measuring time to shorten measuring time of the minimum receiving sensitivity of the radar device even if it is not necessary to completely disconnect the transmission of the radar device as well as to shorten measuring time of the minimum receiving sensitivity of the radar device by generating multiple pseudo signals. SOLUTION: On the radar device carrying out a pulse compression process, the signals digitally synthesized from a plurality of chirp modulation signals having different delay time are generated from a pseudo signal generating circuit 4 as the pseudo signals and multiple pseudo signals are generated at different ranges in a same direction by applying the pulse compression process to the pseudo signals at a signal reception processing circuit 7.
