RADAR INTERFERENCE WAVE REMOVER, RADAR TARGET DETECTOR, RADAR INTERFERENCE WAVE REMOVING PROGRAM, AND RADAR INTERFERENCE WAVE REMOVING METHOD

摘要

PROBLEM TO BE SOLVED: To accurately remove a radar interference wave mixed in a radar received signal even when the electric power of the radar interference wave equals the electric power of a desired wave, not just when the electric power of the radar interference wave is higher than the electric power of the desired wave.SOLUTION: The present disclosure is a radar interference wave remover 1 comprising: an absolute differential value calculation unit 11 for calculating (1) the absolute time differential value of real number data or complex number data of the amplitude of a radar received signal or (2) a representative value or a moving average value in a prescribed time width regarding the absolute time differential value of real number data or complex number data of the amplitude of the radar received signal; and an interference wave removing unit 14 for removing an interference wave mixed in the radar received signal in a time domain where (1) the absolute time differential value of real number data or complex number data of the amplitude of the radar received signal or (2) the representative value or moving average value in the prescribed time width regarding the absolute time differential value of real number data or complex number data of the amplitude of the radar received signal is larger than a prescribed threshold.SELECTED DRAWING: Figure 1
