Abstract: Based on the procedure of trans-atmospheric missile defense interception in each phase, this paper has firstly established a dynamic model for exo-atmospheric interceptor. Then according to the theory of predicted intercepting point (PIP) guidance and firing table interpolation, a method of exo-atmospheric midcourse guidance has been presented to intercept intermediate-range and long-range ballistic target. On this basis, this paper has studied the interceptor deployment zones and the firing/intercept sections according to multiple target trajectories, and the protective zone of one fixed interceptor launch position. With this approach, the effectiveness of the exo-atmospheric interception guidance method has been tested. Finally, considering the penetration measures that ballistic missile may have taken, including maneuver orbital transfer, electronic jamming, infrared bait, etc., the penetration effectiveness that achieved from different measures employed by offensive missile has been analyzed through large sample simulations. For those interceptor deployment positions where the general ballistic target can be hit, the penetration probability of the warhead can be raised up to over 70% with the interference strategies such as maneuver orbital transfer and bait release applied in different phases.
