摘要
分析了非线性CS算法 (NCSA)的成像原理和非线性CS算法造成聚焦图像距离扭曲的原因 ;指出了非线性CS算法在实际应用中其参考频率的选择是唯一的 ,并提出了一种在大斜视角下进行多视处理的方法。计算机仿真证明了该方法的可行性。
In this paper, the principal of nonlinear chirp scaling algorithm is presented and the range distortion of focused image is analyzed. It is proved that the choice of the reference frequency in NCSA is unique. A multiple-look SAR imaging method for the large squint angle is presented. Experimental results show the effectiveness of the presented method.
