针对合成孔径雷达成像中特有的条纹干扰，分析了干扰对图象频谱的影响，提出了利用方向滤波器去除SAR图象中条纹干扰的方法。并从理论上证明了该方法的科学性，给出了方向滤波器的算法步骤。实验结果显示，用方向滤波器算法处理图象，可有效去除干扰，保持图象细节不受损失。

The paper focuses on the stripe noise that only but often occurs in SAR image. The paper analyses the spectrum of the image with noise, discusses the limitations of the repairing methods which always being used and presents a new method, Orientation Filter, to eliminate noise. The correctness of the method is verified in this paper, and the steps of applying the orientation filter are provided. Experiments proved that orientation filter can satisfactory filter the stripe noise and preserves as many target characteristics of original images as possible.
