机动目标跟踪-火控综合系统动态品质分析

研究了机载雷达机动目标跟踪算法，用强迫奇异摄动技术求出了三维追逃微分对策问题的次最优策略。借助于上述算法和策略，建立了一种符合实战情况的跟踪－火控综合系统。从大闭环角度对该综合系统动态品质进行了详细的仿真研究。结果表明，该综合系统能较长时间地锁定目标，准确地实现对目标的三维攻击，并且避免了求解最优控制中经常出现的两点边值问题，使数值计算量大为减少。

ANALYSIS OF DYNAMIC QUALITY FOR MANEUVERING TARGET TRACKING FIRE CONTROL INTEGRATED SYSTEM

The dynamic quality of maneuvering target tracking fire control integrated system is analyzed. Firstly, an algorithm for maneuvering target tracking is suggested, which has higher accuracy of tracking. Secondly, under the assumption of multi time scales separation, by use of the technique of forced singular perturbations, sub optimal control strategies are expressed in a feedback form expressing explicitly the dependence on the measurable target state variables and aircraft performance parameters. Based on the algorithm and strategies above, a tracking fire control integrated system is proposed, which is in accordance with actual combat. Finally, an imaginary air defense scenario is simulated. The system analysis shows that the integrated system has longer lock time, and the burden of numerical calculation is remarkably reduced.
