Polarimetric SAR Coherent Change Detection Method Based on Volume Scattering Constraint

  • 摘要: 相干变化检测(CCD)利用场景中变化区域的失相干特性进行检测,而场景中存在的体散射植被区域及低信噪比区域也呈现低相干特性,对待检测变化区域形成干扰。该文提出一种极化SAR CCD方法,首先利用变化前后SAR图像间的极化相干信息建立加权迹相干统计量,然后利用各个SAR图像内极化通道间的相干信息,通过建立混合GEV分布模型,采用改进EM算法求解各分量参数,建立体散射约束项,最后结合散射功率变化约束项构建极化CCD检验统计量。该方法可在不影响检测性能情况下排除干扰。该文采用变化前后的两幅L波段全极化SAR图像进行方法验证,实验结果及指标参数验证了该方法的正确性与有效性。
