摘要 在寻的导弹的设计过程中,制导导弹的性能通常用脱靶量来度量。目前,对寻的制导系统脱靶量性能的分析仅局限于数值计算和简化模型基础上的近似分析。采用伴随技术和谱方法,研究了零效脱靶量与一般寻的制导系统参数之间的关系,讨论了目标阶跃机动、飞行剩余时间、制导盲区、有效导航比、弹体动态等因素对零效脱靶量的影响,并应用谱方法得到了脱靶量性能的近似解析表达式,为寻的制导系统制导精度分析和精度分配提供了新途径。 The purpose of guidance is to cause a collision between a missile and a specified target.Accordingly,the performance of guidance systems can generally be quantified in terms of the miss distance between the missile and target.The current miss distance analysis is only limited to numerical calculation or approximate analysis based on simplified models.This paper develops the relationship between the zero effort miss distance and the parameters of a generic homing guidance system based on adjoint technology a...
