| 摘 要： | 介绍了合成孔径雷达(SAR)成像特点。探讨了基于方向滤波器和模糊逻辑的模糊方向滤波法,此方法首先将图像进行特征平面增强并模糊化,并获得模糊参数,然后根据模糊规则计算隶属度,以具有相应最大隶属度的像素构成最后滤波结果,达到既滤除噪声又保留图像细节的目的。实验表明此方法优于Lee滤波算法、Esafa算法和加权形态滤波算法。

| Abstract: | The paper introduces the characters of synthetic aperture radar imaging,and discusses the fuzzy direction filtering method based on direction filter and fuzzy logic.The method aggrandizes characteristic-plane to get fuzzy characteristic-plane and its fuzzy parameter firstly.Then computes credibility according to the designed fuzzy rule.The final filtered image is composed of all the pixels with corresponding maximal credibility.It can not only filter noise but also save image in detail.Experiment proves that the proposed method is better than the Lee's filter,the Esafa's algorithm and the weighted morphological filter. |

| Keywords: | computer application SAR image processing fuzzy direction filter characteristic-plane credibility |
