Abstract: A simulation system of the detection of Aegis combat system for the ballistic missile is presented. The propagation model, RF channel and signal processing model for SPY1 radar, SPG62 radar and SM2 seeker are established. The fast evaluation of radar cross section of the ballistic missile is also given. Finally, considering the motion model of AEGIS combat system, the ballistic missile, and the count measures of barrage jamming, the system may be used to simulate the missile penetration to defense of Aegis combat system under the condition of ultra speed flying, well designed trajectory and electronic warfare.

Key words: simulation, AEGIS combat system, ballistic missile penetration, electronic warfare
