摘要
针对高超声速目标拦截问题,提出了拦截器的末段交战窗口(TEW)快速生成方法,该窗口表征了所有可行的末段交战阵位。首先,针对高超声速非机动目标建立了解析形式的拦截条件。在此基础上,针对非机动目标和机动目标,依次推导了TEW边界的解析方程。同时,根据拦截器的最小和最大初始航向角,定义并计算了TEW内所有位置的可控裕度。最后,通过对高超声速目标TEW仿真,验证了所提出方法的有效性,并分析了TEW边界和可控裕度的影响因素。与传统数值方法相比,本文解析方法生成的TEW边界一致,但计算耗时大幅减小,具有在线使用的潜力。此外,仿真结果也表明,当目标信息存在测量误差时,所提出的TEW生成方法依然有效。
In this paper,a generation method of terminal engagement window(TEW),which describes the set of feasible engagement positions in the terminal guidance phase,is developed for the interception of hypersonic targets.Firstly,an analytical interception condition is established.On this basis,the analytical solutions of the TEW boundary are successively derived for the non-maneuvering and maneuvering targets.Then,a controllable margin is defined and calculated for each position in the TEW according to the interceptor’s minimum and maximum initial heading angles.Finally,the TEW generation method is verified by simulations,and the influence factors are analyzed for the TEW boundary together with the controllable margin.Compared with the traditional numerical approaches,the proposed analytical approach has the consistent results but much lower computational cost,and thus is more capable to generate a TEW onboard.The results also indicate that the generation method is still effective when the measurement errors of the target exist.
