Target Detection Method of the LFM Radar Signal with Multiple Polarization Agility

This paper discusses a linear frequency modulation (LFM) radar signal with multiple polarization agility for the full polarization radar system. The LFM signal is adopted inside each transmitted pulse and the range resolution can be improved through pulse compression technique. The polarization state of the transmitted signal can be changed among several polarization states, and the target can be discriminated from the interference signal through polarization estimation and detection. The signal processing method is introduced. The research results reveal that the target can be effectively detected based on their difference in polarization domain after the target and interference are separated in the range.
