| 摘 要： | 该文结合SAR领域的两种重要技术极化和多通道，提出了在双通道极化合成孔径雷达(D-PolSAR)系统中同时抑制压制和欺骗干扰的方法。文章首先建立了D-PolSAR系统模型，分析了在这一系统下的信号模型和干扰模型；然后分析干扰信号与真实目标信号在D-PolSAR系统下的差异，提出了基于相位补偿的双通道相消方法来同时抑制压制干扰和欺骗干扰，仿真实验证明该方法的有效性。

| Abstract: | 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. |
