SAR Target recogntion 高分辨率SAR图像 目标电磁散射特性 Propose an improved hybrid method (HM) of microwave backscattering calculation and 3D modeling of target. Based on the HM,the high-frequency radar cross section (RCS) of complex military targets is calculated and high resolution inversed SAR (ISAR) image is simulated. The method of affine transform is used to extract the invariant features of the image contour of several types of airplanes. The image contours of several airplanes are real-time acquired by using space distribution image of backscatter characteristics through Cellular Neural Networks. Then, the target can be recognized automatically from simulated ISAR image. A series of experiments are presented using the high resolution SAR image acquired by the Chinese airborne SAR system.
