摘要:
针对半主动自寻的合成孔径雷达制导导弹发射后,战斗机、导弹的运动状态如何同时满足成像分辨率和脱靶量要求的问题,提出一种基于逆最优控制方法的战斗机引导律和导弹制导律。将成像分辨率对战斗机及导弹运动状态的双边约束,转化为对战斗机目标线角速度的单边约束;将脱靶量转化为对导弹目标线角速度的约束,从而实现导弹运动的自主性;建立含有待定权值系数的性能指标函数,根据所建立的战斗机引导系统和导弹制导系统的动态调节时间确定该系数,逆向得出最优引导律和最优制导律,仿真结果验证了该算法的有效性。

Abstract:
To meet the requirements of resolution at the azimuth and miss distance for motion states of Bi-SAR platforms which indicates the fighter aircraft and the semi-active homing SAR-guided missile after launch, guidance laws for the aircraft and missile based on inverse control algorithm are proposed. Two-sided constraints due to resolution for their motion states is converted to one-sided constraint for the aircraft's angular velocity of line of sight, and miss distance is considered as only constraint for the missile's angular velocity of line of sight to implement its autonomy of motion. Performance index function containing undetermined coefficients is build and the coefficients are calculated according to dynamic tuning time for both guiding systems, and their optimal guidance laws are derived inversely. Simulation results demonstrate the validity of the algorithm.
