摘要
大气层外动能拦截器末制导阶段的场景参数对末端拦截过程影响较大,本文分析了初始视线角和初始视线角转率对末端拦截的影响。分析表明,由初始视线角构成的参数域可分为"拦截域"、"突防域一"和"突防域二"3个区域,其形成的主要原因为相对速度差异;"拦截域"对初始视线转率敏感,略微增大初始视线转率可致使"拦截域"明显缩小,而相应的"突防域二"则扩大;由初始视线转率构成的"拦截域"形状为矩形。分析结果对末端拦截具有重要意义。
The scene parameters of exoatmospheric interceptor in endgame have great effects on the interception.The impact on the initial angle of LOS and the initial LOS rate for the interception in endgame is investigated in the present cross-sectional study.It indicates that the parameter field which is established by the initial angle of LOS can be formed by the ＂intercept field＂,the ＂penetration field 1＂ and the ＂penetration field 2＂.The main reason is the difference of relative velocity.The ＂intercept field＂ is sensitive to the initial LOS rate,and it shrinks obviously when the initial LOS rate is aggrandized appreciably and the ＂penetration field 2＂ is extended at one time.The shape of the ＂intercept field＂ which is structured by initial LOS rate is rectangle.The significance of interception in endgame is realized regarding the analyzed results.
