Phase gradient auto - focus algorithm ( pga ) and rank one phase estimation auto - focus algorithm ( rope ) satisfying high - resolution air - borne sar image formation needs are analyzed . aimed at disadvantages of pga and rope algorithms , improved rank one phase estimation auto - focus algorithm ( irope ) is introduced . at last , combining fsa and irope algorithms , using air - borne sar actual flight data , the algorithms " feasibility and validity are validated
第三，针对相位误差对图像质量的影响进行了定性分析，同时对多普勒参数估计的必要性及其几种算法进行了讨论；接着系统研究了适合于高分辨率机载sar成像要求的相位梯度自聚焦算法( pga )和秩一相位估计自聚焦算法( rope ) ，并针对pga和rope算法的不足之处，介绍了改进的秩一相位估计自聚焦算法( irope ) ；最后，结合fsa成像算法和irope自聚焦算法，以机载sar实际飞行数据为基础，对算法的可行性和有效性进行验证。
