天基信息引导下反导武器系统拦截窗口分析

Analysis of Intercept Window of Anti-Missile System under the Cueing of Space-Based Information

基于分析天基信息对反导武器系统的引导方式和引导精度,提出了能够评估拦截效能的反导武器系统拦截窗口的计算方法;建立了不同预警方式下的预警信息发出时刻和天基信息引导下的武器系统雷达发现目标时间的计算模型。通过仿真表明天基预警信息能够为反导武器系统提供充足的作战准备时间,在天基引导信息引导下,武器系统跟踪制导雷达能够更准确快速地跟踪制导雷达发现目标,改善引导信息的精度,增大拦截时间窗口和空间窗口并提高拦截弹拦截更远射程目标的能力。

Firstly,the cueing method and cueing accuracy of the space-based information for anti-missile weapon system are analyzed. Then,the method of calculating the intercept window of anti-missile system which can evaluate the interception efficiency is put forward. The calculation model of the early warning information issuing time with different warning mode and the time that guidance radar need to find target under the cueing of space-based information is established. Lastly, the simulation results indicate that the space-based warning information can provide sufficient preparation time for the anti-missile system and the guidance radar cued by the space-based information can be faster and more accurate to find the target. Increased accuracy of cueing information can increase the intercept time window and space window,and raise the ability of the interceptor to intercept farther range target.
