STK在导弹预警卫星仿真中的应用

摘要

导弹预警卫星是美国国家导弹防御（NMD）系统中最重要的装备,是战略预警的有效手段,在战争中起着其它装备无法替代的重要作用。总结了美国导弹预警卫星的发展历程,并用卫星仿真工具包（STK）对国防支援计划（DSP）和天基红外系统（SBIRS）预警卫星的布局以及工作模式进行了仿真建模。%The missile early warning satellite is the most important equipment of national missile defense（NMD） system and an effective measure for strategic early warning,it plays an indispensable role in wars.This article summarizes the development course of missile early warning satellite in America,and simulates and builds the models for the distribution and work modes of missile early warning satellite of defense support program（DSP） and space-based infrared system（SBIRS） through the satellite tool kit（STK）.
