【摘要】 为解决突防弹对EKV定位问题,利用EKV逆轨拦截特点,提出天基跟踪与监视系统(STSS)单星红外探测结合突防弹导航信息对EKV定位算法。EKV逆轨拦截时在突防弹道平面内,STSS红外探测器到EKV的视线与弹道平面的交点就是EKV的位置,可根据星载探测器位置及突防弹导航信息解算。论证了STSS红外探测器对EKV的可探测性,阐述了算法实现步骤并进行数值仿真,分析了定位误差及其成因。结果表明,该算法无需新增探测设备就可实现突防弹对EKV的定位。更多还原

【Abstract】 To resolve the problem of penetration missile’s localization to EKV,considering EKV head-on impact,a localization algorithm to EKV by space tracking and surveillance system(STSS) single satellite infrared detection and penetration missile navigation information is proposed.During its head-on interception,EKV locates in the ballistic plane of penetration missile.The intersection point of sight light from STSS infrared detector to EKV and penetration missile’s ballistic plane is the location of EKV.The EKV position data can be calculated according to location of satellite-borne detector and penetration missile’s navigation information.The feasibility that STSS infrared sensor detects the EKV is demonstrated.Then the algorithm implement approach is expatiated and the numeral simulation is carried out.Finally,the localization error and its reasons are analyzed.It is indicated that the algorithm can locate the EKV situation for penetration missile without additional detection equipment.更多还原
