Jamming Suppression in D-PolSAR System
双通道极化SAR干扰抑制

In the paper, making use of two key techniques in SAR domain—mutichannel SAR and PolSAR, a method to suppress both the blanketing jamming and the deceptive jamming is provided in Dual-channel PolSAR (D-PolSAR) system. First, the model of the D-PolSAR system is established, and the signal and jamming in the D-PolSAR system are analyzed; then by comparing the difference between jamming and real signal, a Two-Channel-Cancellation(TCC) method based on phase compensation is proposed to suppress these two types of jamming. The simulation results validate the effectiveness of proposed method.
