提出了基于遗传算法进行逆合成孔径雷达运动补偿的新算法.针对遗传算法解的收敛性问题,在遗传算法中采用了最优个体保存策略,使得解以概率1收敛于全局最优解;针对遗传算法运算量大的问题,提出了采用运动补偿后最小熵和最小距离作为适应度函数,由此形成2种称为GAMCE和GAMCD的ISAR运动补偿新算法.仿真数据和实测数据验证了所提新算法的有效性.

[Abstract]
A new method of ISAR motion compensation based on genetic algorithm is suggested.Aiming to guarantee that GAMIC(genetic algorithm of minimum image entropy)and GAMIE(genetic algorithm of maximum image contrast) converges on the optimum solution,the best individual preserving tactic is adopted.To reduce the heavy computation load of GAMIC and GAMIE,the minimum range and the minimum entropy of the range compensation,instead of image,are taken as the fitness function of genetic algorithm.Owing to the improvemen...
