针对PolSAR的全极化卷积噪声遮蔽式干扰方法

摘要

提出了针对PolSAR的全极化卷积噪声遮蔽式干扰方法，给出了干扰机的设计方案、基本原理与工作流程，推导了受干扰PolSAR的信号模型，分析了干扰功率和信号功率在PolSAR成像处理中获得的不同增益。通过实验仿真考察了电子干扰对PolSAR点目标质量和图像纹理信息的影响，即不同的质量参数变化趋势相互统一并具有典型的变化特征，从而验证了该方法的有效性。%A scheme with jammer design of full-polarization jamming on PolSAR using convolu-tional noise is presented. Then the signal model under jamming is deduced, which denots the different gains between jamming power and signal power in PolSAR imaging process. Finally the influence of electronic jamming on PolSAR point target and image texture is addressed by simu-lation experiment, which verifies the scheme presented.
