基于制导/估计综合设计的协同制导律

基于普通分离原理,将反导作战噪声环境中拦截高速机动目标的制导问题考虑为一类非线性、非高斯追逃拦截问题.引入追逃未达集概念,利用几何方法将估计器设计方法结合到制导律的设计中,通过理论推导综合设计了估计器和制导律,并在此基础上,在目标函数中,引入包围因子,对多拦截器协同制导律进行了研究.数值仿真验证了基于制导/估计综合设计的协同制导律的制导性能和有效性.

Cooperative Guidance Law Based on Integration Design of Guidance and Estimation

The guidance systems based on separately the designing of the estimator and the guidance law have not been suboptimal. This paper addresses the problem of guiding a missile towards an evading agile target in the presence of noisy measurements. A new guidance law that complies with the optimal estimator under the guidelines of the GST is proposed. The conception of miss-set is termed and a geometric approach is utilized. As a result, The new cooperative guidance law is designed. The numerical simulation for a realistic engagement scenario demonstrates the performance and viability of the proposed method.
