根据多飞行器协同制导的特点和要求,提出了一种适用于领弹-从弹策略的时间协同制导结构。该时间协同制导结构由个体独立导引控制和系统总体协调控制两部分构成。由位于领弹中的中央处理单元进行协调控制,占主要地位的领弹通过向从弹广播协同信息以实现整体的协同控制,协同信息包括期望攻击时间和领弹与目标的相对运动信息。针对此结构的特点和从弹无导引头的要求,给出了具体可行的视线角速率提取算法,从而降低了从弹弹载计算和探测设备的要求。从弹根据协同信息调整飞行轨迹,使得各弹同时到达目标,并且综合代价最小。仿真结果表明,采用此制导结构能够有效地实现协同攻击,验证了其良好的性能,使得多枚飞行器的整体性能达到全局最优。
According to the characteristics and requirements of multi-aircraft cooperative guidance, a time coordinated guidance structure suitable for the pilot-bomb strategy is proposed. The time collaborative guidance structure consists of independent guidance and control of the individual and the overall coordination and control of the system. Coordinated control by the central processing unit located in the firing bomb, the dominant bullet broadcasts synergistic information to control the overall synergetic information from the bomb, and the synergistic information includes expected movement time and relative movement information between the bomb and the target. According to the characteristics of this structure and the requirements of the missile-free seeker, a feasible algorithm for extracting the line-of-sight angular rate is proposed, which reduces the requirements of the equipment for missile calculation and detection. From the bomb according to the coordinated information to adjust the flight path, making the bullets reach the target at the same time, and the overall cost is minimal. The simulation results show that this guidance structure can effectively achieve cooperative attack, verify its good performance, and make the overall performance of multiple aircraft reach the global optimum.
