传统的各种制导律都是以获得最小脱靶量为最终目标,没有考虑到导弹击中目标时刻的末端落角。为了保证非自旋再入体完成精确打击目标的任务,针对非自旋再入体垂直打击目标的制导问题,设计了一种带落角约束的扩展比例导引律。仿真研究表明,所设计的末制导律能够保证非自旋再入体命中目标时的脱靶量和末端落角都能满足要求,可以为开展近空间非自旋再入体制导问题的研究提供测试平台。
The traditional guidance laws all take the minimum miss distance as the ultimate goal and do not take into account the terminal falling angle when the missiles hit the target. In order to ensure the target of non-spin reentry to strike accurately, aiming at the guidance problem of vertical strike target of nonspin reentrant body, an extended proportional navigation law with drop angle constraint was designed. The simulation results show that the designed final guidance law can guarantee that the miss distance and tip angle can meet the requirements of non-spin reentry target hit, and can provide the test for the research on guidance of near-space non-spin reentry system platform.
