| Abstract: | The performance of deblurring of synthetic aperture radar(SAR) images based on wavelet transform is studied.Several normal kinds of adaptive filtering methods are introduced.The performance of the presented algorithm in restraining the correlative speckle noise and keeping the edge of the image is examined.The result shows that the algorithm filters the SAR image speckle noise efficiently,meanwhile it has much stronger ability to maintain the detail information. |
| Keywords: | synthetic aperture radar(SAR) image speckle noise wavelet transform filtering |
