In view of the strategic defense problem, according to different operations two scenes including a single-directional threat and a fan-shaped threat are established, and the incoming targets are intercepted at the middle segment. According to the characteristics of the selected interceptor and the incoming missile, the space killing area of the interceptor mode and the model of protection zone and the covering angle of the ground assets are established, and the weapon deployment model under the two scene defense systems is established. The model is optimized by the comprehensive interception efficiency, the ground assets covering angle, and the deployment cost. The validity of the deployment model method is verified by a concrete example. The research results have certain reference value for the application of antimissile warfare.

Early warning system formed by infrared satellites of both high and low orbits is designed, and high thrown interception scheme is proposed to cope with the threat of hypersonic glide warhead. Dynamic model is established based on performance parameters of typical glide warhead and THAAD. Detection process and interception process are simulated by STK and Matlab softwares. The results shows that the infrared satellite constellation can achieve better binary coverage, the high thrown interception scheme has longer intercept window and bigger defense extent, the correcting capability of midcourse guidance is outstanding, and acceleration of terminal guidance is appropriate.
