| 随着战场电磁环境日趋复杂，当前体制下的RWR/ESM正逐渐暴露出其误警率高、漏警
率大和告警时间长等严重问题，其根本原因是由于接收机测量体制引起的脉冲丢失问题，导
致威胁信号源的截获概率降低。结合RWR/ESM测量体制，对时分制频段处理方法引起的脉冲
丢失进行理论分析，推导出工程上可行的应用公式，在此基础上提出了一种基于脉冲密度分
配系统资源的改进方法，并结合仿真结果对两种方法引起的脉冲丢失做了对比分析。研究结
果为今后新型RWR/ESM的研制提供了理论参考。 |

| Abstract: |
| With the electromagnetic environments of war-field being so intricate and com
plex, the high false alarm rate,big missed detection rate and long warning tim
e are big problems faced by the RWR/ESM（Radar Warning Receiver/Electronic Su
pport Measure）receiver. The basic reason is the pulse loss caused by measuremen
t system that leads to the reduce of the intercept of threaten signal.In combination
with measurement system this paper analyzes the pulse loss caused by time divis
ion, and infers comput
ational formula of the pulse loss probability.On this base,an improved
method based on pluse density is proposed to distribute system resource.The pul
ses loss caused by the two methods are compared according to simulations.The re
search in this paper provides theoretical reference for developing new RW
R/ESM in the future. |
