摘要介绍了利用多普勒波束锐化（DBS）雷达导引头对空空导弹进行末制导的弹道优化技术。末制导问题的特点是隐身地形跟踪阶段，随后是爬升和俯冲到目标上（“狩猎”轨迹）。DBS雷达的成像特性对轨迹施加了额外的方位角平面约束，这些约束必须纳入优化过程。各个任务阶段是相互关联的，性能目标与硬件约束发生冲突。轨迹优化器用于生成满足各种任务要求的离线开环控制。数值算例说明了该方法的有效性。
The use of trajectory optimization techniques is presented for the terminal guidance of an air-to-surface missile using a Doppler beam sharpening (DBS) radar seeker. The terminal guidance problem is characterized by a stealthy terrain-following phase that is followed by a climb and dive onto the target (a "bunt" trajectory). The imaging properties of DBS radars impose additional azimuth plane constraints on the trajectory that have to be incorporated into the optimization process. The various mission phases are interrelated, and the performance objectives come into conflict with the hardware constraints. The trajectory optimizer is used to generate offline open-loop controls that satisfy the various mission requirements. Numerical examples are used to illustrate the method and its efficacy.
