A Kind of Signal Processing Method for the Polarization Phased Array Radar

This paper discusses a kind of polarization phased array radar system and its signal processing method. The polarization signal processing technology is introduced to improve the detection performance and anti-jamming ability of the radars. In order to achieve the performance of low probability of intercept (LPI) for the transmitted signal, the linear frequency modulation (LFM) is adopted inside each pulse and the frequency coded technology is adopted among pulses. The radar system can received the scatted signal of the target through dual polarization channels simultaneously and the polarization information of the target scatted signal can be obtained. In signal processing, the polarization parameter estimation and polarization detection technology are used. The basic structure of the polarization phased array radar is introduced, and the specific LFM pulse compression and polarization detection method are discussed. The analysis results in this paper can provide a reference for the design of the polarization phased array radar.
