Abstract:

The development of ground-based midcourse defense interceptor with its exo-atmospheric kill vehicle and booster is researched systematically. The flight test of ground-based interceptor and the development plan of next-generation interceptor are described. The population parameters and boost engine parameters of ground-based interceptor are anti-designed based on its public information. The shoot table and spatiotemporal characteristics and intercept airspace of two-level and three-level ground-based interceptor are simulated.

Key words: ground-based midcourse defense, ground-based interceptor, exo-atmospheric kill vehicle, orbital boost vehicle（OBV）, intercept airspace

摘要：

系统性跟踪研究了美国陆基中段防御拦截弹及其大气层外拦截器(exo-atmospheric kill vehicle，EKV)、助推器的系列发展情况，阐述了陆基拦截弹的飞行试验情况及下一代拦截弹的研发安排，基于陆基拦截弹公开信息对其总体参数与助推发动机参数进行了反设计，并对陆基拦截弹二级/三级状态飞行射表及其时空特性、拦截空域进行了仿真分析。
