A Method of Extracting Radar Deception in Polarization Agile Radar.

In order to simplify the separation of radar echo and deception and to get the Jones vector of deception, a simple and convenient method to extract radar deception is proposed. By transmitting a group of relative polarization agile signals, the scattered wave and deception can be separated during the calculation of the signal output by the receiver, while utilizing the polarization effect of the target and the constant polarization state of deception. Compared with existing interference feature extraction algorithms, resources can be saved when this algorithm is implemented in single chip. The simulation results show that the relative errors of the calculation are less than 10% , when INR is more than 11.8 dB. [ABSTRACT FROM AUTHOR]
