：提出针对单极化合成孔径雷达(SAR)图像相干斑滤波算法性能的分层检验模型和综合评价 方法。模型分相干斑抑制程度和目标微波后向散射系数保持程度两个层次，包含的指标有等效视数、信号 杂渡比、回波辐射度损失、均值偏差、空间分辨率损失和峰值旁瓣比偏差六项-: Unipolar against synthetic aperture radar (SAR) image speckle filtering algorithm hierarchical test model performance and integrated evaluation. Model sub-speckle suppression and objectives of the degree of microwave backscattering coefficient to maintain the level of two levels, including the indicators have the equivalent depending on the number of signals crossing miscellaneous ratio, radiometric echo loss, the mean deviation, loss of spatial resolution and peak sidelobe than the deviation of the six
