摘　　要：随着雷达技术的发展,雷达系统越来越复杂,对雷达系统的模拟也趋于困难,如模拟的时间费用等。传统的蒙特卡罗模拟方法已经不能满足这种发展趋势,必须采用改进的模拟方法。以稀有事件—雷达虚警为例,介绍重要采样法在雷达虚警概率模拟中的应用,比较二进制滑窗积累器和四进制积累器的虚警概率性能,证明重要采样法在时间费用上的优势。With the development of radar technology the radar systems become to be more and more complex. And the simulation to them becomes more difficult. The Monte Carlo Method is losing it's importance in this area. And the ameliorative simulation methods are wanted. It introduces the apply of importance sampling on radar false-alarm rate on singularity event-radar false alarm. Then it compares the false alarm performance of binary integrator and quarto integrator and prove the advantage of time based on importance sampling.
