介绍了非线性啁啾缩放算法（NCSA）的原理，分析了大斜视下非线性距离变化对二次距离压缩（SRC）的影响。基于SRC随非线性范围变化的假设，提出了一种改进的NCSA算法，改进了散射的聚焦特性。理论分析和实验结果均表明了该方法的有效性。
The principle of the nonlinear chirp scaling algorithm (NCSA) is introduced, and the influence of the nonlinear range variation on secondary range compression (SRC) under large squint is analyzed. Based on the assumption of SRC variation with nonlinear range, an improved NCSA is proposed and the focusing feature of the scatter is improved. Both theoretical analysis and experimental results show the effectiveness of the method.
