| Abstract: |
| In this paper, the wavenumber domain algorithm for large processing-angle UWB-SAR imagery is briefly described. Then the content and necessities of Stolt Interpolation are studied. And some intpolating methods are presented to work for Stolt Interpolation. Lastly, with these methods, many emulations are made and good focusing results obtained. It is clear that all methods introduced are efficient. |
