针对Goldstein枝切线法存在的问题,根据残差点的分布特点,提出了一种新的干涉合成孔径雷达相位解缠方法.该方法首先对邻近偶极子对进行预处理,生成独立且长度很短的枝切线,使用自适应遗传模拟退火算法计算剩余正负残差点的优化组合,不仅在短时间内设置出总体长度较短的枝切线,且有效地避免了大面积“孤岛”出现.实验结果表明,相比于几种典型的相位解缠算法,该方法在时间和精度上具有优越性.
Aiming at the existing problems of Goldstein tangent line method, a new method of phase unwrapping interferometric synthetic aperture radar is proposed according to the distribution of residual points. The method firstly preprocesses adjacent dipole pairs to generate independent and short length , The optimal combination of the residual positive and negative residuals is calculated by using the adaptive genetic simulated annealing algorithm, which not only sets the shorter total length of the tangent lines in a short time, but also effectively avoids the appearance of large island. The experimental results show that this method is superior in time and accuracy compared with several typical phase unwrapping algorithms.
