摘要: |
在简要总结大处理角UWB-SAR成像处理有关难点后, 本文提出将波数域成像算法(Ω-K算法)应用于UWB-SAR成像处理; 然后介绍了Ω-K算法的原理并对其中存在的Stolt插值等问题进行了详细分析和深入探讨; 最后结合所建立的UWB-SAR回波模型对Ω-K算法进行了仿真, 研究表明这种成像方法具有较好的聚焦效果。 |

Abstract: |
After summarizing some difficulties of large processing-angle UWB-SAR imagery briefly, the wavenumber domain algorithm (Ω-K algorithm) is used for UWB-SAR imagery in this paper. Then the theory of Ω-K algorithm is described and the problems like Stolt Interpolating are analyzed in detail. Eventually, numerical experiments on simulated echo model are presented. All results show that this algorithm has good focusing capabilities. |
Keywords: UWB-SAR, wavenumber domain algorithm, Stolt interpolating |
