In order to achieve more robust image processing and analysis,it＇s necessary to investigate the correlations between the statistical features used in the state of the art and the sensor parameters.The research is on the robustness of six kinds of statistical features against the wavelength（L band,C band and X band） of the synthetic aperture radar（SAR）.First the measurement of robustness of statistical features is defined,and then the comparison and analysis are presented in our experiment.In addition,the experiment also shows that statistical features of different terrains have different change while wavelength changes.%传感器参数不同会导致图像灰度与表象特征不同,进一步会影响到统计特征表达。因此有必要系统研究常用统计特征与传感器参数之间的相关性,从而实现更加抗差的图像处理与分析。研究目前常用的6种图像统计特征,在合成孔径雷达（SAR）波长变化时（L波段、C波段和X波段）的抗差性。试验中,对抗差性能指标作出定义,并对不同统计特征的抗差性做出了比较与分析。试验结果发现,不同统计特征对波长变化的抗差性不同,同时图像特征在不同地形时随波长变化的规律也不一致。
