A Research on the Multi-aperture Wide-Swath SAR Imaging Method
-
摘要: 该文提出了一种新的基于距离向多孔径接收宽测绘带合成孔径雷达(SAR)成像方法。首先对这种成像方法进行了严格的论证,并证明了运算中的加权矩阵为良态矩阵,然后分析了这种成像方法的计算量,讨论了这种宽测绘带SAR的信噪比,最后给出了仿真结果。Abstract: A new imaging method is proposed for multi-aperture wide-swath Synthetic Aperture Radar (SAR) in this paper. The imaging algorithm is proved theoretically, and the weighting matrix is proved to be in good condition. The computational complexity of the imaging algorithm is analyzed. The Signal-to-Noise Ratio (SNR) of this kind of multi-aperture wide-swath SAR is discussed. Finally, the simulation result is presented.
