国会研究所的导弹防卫专家，斯蒂芬·希尔德雷斯在美国国会政府改革委员会国家安全专家组的听证会上就同一问题发表陈述时，强调制造装备核弹头的越洋导弹所涉及的划时代技术挑战。

The constraints of the missile flying with SAR at the flight time are built, and the missile command acceleration is used as control variables to set up the objective function about the dwell time and the desired azimuth resolution. The control variables are optimized using the genetic algorithm, and an optimal trajectory is gotten.

首先建立了弹载SAR条件下导弹飞行的约束，然后以导弹指令加速度为优化变量，构造了与方位分辨率和波束驻留时间相关的目标函数，采用遗传算法进行寻优，设计得到了弹载SAR平台的优化弹道。
