针对高超声速飞行器动态禁飞区规避制导问题,提出一种基于模糊理论的自适应触角探测制导方法。首先,面对由于雷达探测产生的禁飞区域变化问题,进行动态禁飞区建模及耦合性分析;然后针对动态禁飞区规避制导问题,构建基于触角探测的动态禁飞区机动制导框架,同时设计安全度准则探测信息,结合模糊理论提出面向动态禁飞区的自适应触角探测制导策略;最后,对本文所提出的方法进行数学仿真验证,结果表明自适应触角探测制导方法能够有效解决动态禁飞区耦合下的规避制导问题,并且通过与固定触角方法进行对比测试,表明本文方法在提高规避效果、节省飞行能量等方面均有良好表现。

An adaptive tentacles detection and guidance method based on fuzzy theory is proposed to solve the problem of dynamic no-fly zone avoidance guidance of hypersonic vehicles.Firstly,dynamic no-fly zone modeling and coupling analysis is carried out in the face of the problem of no-fly zone variation caused by radar detection.Then,aiming at the dynamic no-fly zone avoidance guidance problem,a dynamic no-fly zone maneuvering guidance framework based on tentacles detection is constructed,and the detection information based on the safety criterion is designed.Finally,the proposed method is verified by mathematical simulation,and the results show that the adaptive tentacles detection guidance method can effectively solve the evasive guidance problem under the dynamic no-fly zone coupling,and the comparison test with the fixed tentacles method shows that the proposed method has good performance in improving the evasive effect and saving flight energy.
