摘要： 为实现对于机动目标的有效拦截，针对更符合实际的目标拦截情形，给出了一种考虑自动驾驶仪动态特性(autopilot dynamics, AD)的制导律设计方法. 该方法将拦截问题分解为一个双方优化和一个单方优化问题，分开考虑目标和拦截导弹的AD. 双方优化只考虑目标AD，推导目标的最优规避策略；而单方优化只考虑拦截导弹AD，并基于目标最优规避策略进行拦截导弹最优寻的制导律设计. 仿真结果表明，该制导律考虑AD的情形是合理的，相比于传统单一优化方法，寻的性能更好，对拦截导弹机动性要求较低.

Abstract: For maneuvering target interception, a new method for guidance law design is presented, which takes into account the autopilot dynamics, and is more realistic and effective. Instead of being determined in a single optimization problem, the interceptor strategy and target strategy are determined separately in two separate optimization problems. First, the target strategy is derived in a two-sided optimization problem that
does not consider the interceptor’s lag. The interceptor homing guidance law is then derived in a one-sided optimization problem that considers the interceptor’s lag subject to the target strategy derived in the first optimization problem. Simulation results show that the proposed optimal guidance law can improve performance and requires low maneuverability by properly considering the autopilot lag.
