| 摘 要： | 基于Pearson分布族模型反演SAR影像的分布模型，将统计类型的确定结果用于弱对比度SAR影像的对比度增强。这种方法具有保持SAR影像直方图的分布特性与偏斜特性的优点，且避免了普通直方图规定的盲目性。

| Abstract: | Distribution model of SAR images has been inverted from Pearson distribution family with back calculation in this paper, which is helpful to enhance the contrast of SAR images. With this method, the distribution character of histogram and its skewness are preserved well, thus avoid being blindsided in the procedure of histogram specification. |
