摘要
空间环境的日益恶化给远程弹道导弹空间飞行安全带来了严重威胁。针对空间碎片的数目繁多使得导弹与空间碎片碰撞预警耗时很长的问题,为了减少碰撞预警时间,提高预警效率,分析碰撞预警模型和多线程多CPU特点,提出了基于多线程技术的远程弹道导弹与空间碎片碰撞预警算法,并运用仿真比较了算法的预警效率。仿真表明该算法能有效减少预警时间,提高预警效率。该算法可为发射前碰撞预警提供技术支持。
The flying space environment has been deteriorating,and it is very long to calculate where impact occurs between missile and space debris because of large amount of space debris.According to the analysis of traditional alert model and the characters of multi-thread and multi-CPU,a model of impact alert based on multi-thread technique was established.The simulation results indicate that the alert time can be effectively reduced and the alert efficiency can be advanced using the parallel algorithm..
