Method for improving spatial resolution of big-front-slope SAR image of aircraft platform

The invention proposes a method for improving the spatial resolution of a big-front-slope SAR image of an aircraft platform, and the method comprises the steps: setting a Gaussian kernel, determininga Gaussian filter, determining the gray level change value of each pixel in the SAR image, determining the difference feature value of the pixels, processing the SAR image through a total variation model, and obtaining the SAR image with the improved resolution. The method achieves the noise inhibition of the SAR image through a weight factor, and a big weight factor is applied in a smooth regionof an image, so as to inhibit the noise, thereby reducing the noise level of a radar image. A small weight factor is applied in an edge region, so as to maintain the edge and detail information of theimage, to enhance the details, and to enable the contour of the edge of the image to be more apparent. Therefore, the method gives consideration to the noise inhibition and detail maintaining. 本发明提出种增强飞行器平台大前斜SAR图像空间分辨能力的方法，通过
