摘　　要：针对远程地空导弹在拦截远距离目标时,容易被敌方防御系统发现并拦截的问题,提出了基于免疫变结构的远程地空导弹机动突防弹道。该弹道根据视线角速率跟踪有界振荡信号的思想,应用滑模变结构理论,考虑中末制导交班的约束条件,设计了一种机动突防中制导律,同时应用免疫反馈原理对滑模变结构控制中出现的抖振进行抑制和补偿。仿真分析表明,提出的机动突防制导律的正确性和有效性,该制导律显著地提高了远程地空导弹的机动突防能力。Long time of fight is always needed when a long-distance air defense missile intercept far distance tar-gets？ which resulting in high chances to be detected and intercepted by enemy？s defensive system. To solve this problem, a midcourse maneuver penetration trajectory was proposed. With the idea of angular rate of lin^of- sight tracking bounded oscillation signal and the theory of sliding mode control, a midcourse guidance law based on virtual target？s maneuver penetration was designed under the constraint of handover between midcourse guid-ance and compensate. The ant-interference immunity feedback is used to control and compensate the buffeting appeared in sliding mode variable structure. The guidance law was approved to be correct and valid in simula-tion, and shown to improve the maneuver penetration ability of long-distance air defense missile significantly in penetration probability evaluation.
