| 摘要: |
| 脉冲交叠是影响RWR/ESM系统效能的重要因素之一。针对典型四通道比幅测向体制的R
WR/ESM系统中因分频段、分象限形成的多通道信号感知结构，采用仿真方式，对多辐射源信
号进入RWR/ESM系统后的脉冲交叠情况进行了统计，发现RWR/ESM信道中脉冲交叠的规律：
N（N≥2）脉冲交叠比N-1脉冲交叠基本上低一个数量级；且脉冲交叠对不同辐射源信
号序列有不同影响，脉冲交叠同时使得后续的脉冲正确配对比率比较低。 |

| Abstract: |
| Pulses overlapping is one of key factors that affect RWR/ESM system. The mul
ti-sensor channels′ characteristic of a typical 4-channel-Amplitude-Comp
aring DF(Direction Finding) RWR/ESM system is studied in circumstance of multi
-radiant objects by simulation and statistics. A law of pulses overlapping in
RWR/ESM′s multi-sensor channels is found: the ratio of N+1（N≥2）pulses
overlapping is lower in quantitatively level than that of N pulses overlappi
ng；pulses overlapping effects for different pulse streams are different, and ma
ke the ratio of pulses right matching smaller. |
| Key words: RWR ESM pulse overlapping pulse right matching signal sensor |
