Resolution enhancement of SAR image using the modified IBP method

摘要：

Super resolution (SR) technique can produce a high resolution (HR) image from a set of low-resolution (LR) images with complementary information. This paper proposes a modified iterative back projection (IBP) method for SAR image resolution enhancement. In this method, a SR image is assumed and modification which contains the different high frequency information of LR images is back projected to it to get an ideal HR image. Compared with the original IBP, the modified IBP method is simpler and the modification is more accurate to speed up the iteration Both simulated and real SAR images are used to verify the validity of the method. The results show that details and definition of the LR image processed with the method are effectively improved.
