临的重要问题之一。从理论上对分频段RWR/ESM接收机的脉冲重叠概率进行了分析，推导
出多频段RWR/ESM接收机的脉冲重叠概率计算公式。仿真结果虽然验证了分频段可以降低RWR

定分频段数量的RWR/ESM接收机，在特定的电磁环境下，存在最佳的频段划分方式可使RWR
/ESM接收机的脉冲重叠概率取得最小值。 |

| Abstract: |
| The electromagnetic environment of war-field is so intricate and com
plex, and radar pulse signals are very rich, overlapping pulse is a big problem
faced by the RWR/ESM（Radar Warning Receiver/Electronic Support Measure）rec
eiver. This paper analyses the method of dividing alarming frequency into some m
ulti-band, and infers computational formula of the overlapping pulses probabilit
y after frequency dividing. Simulations indicate that frequency-dividing techniq
ue can reduce the overlapping pulses probability, but the fixed frequency dividi
ng can not minimize the overlapping pulses probability. For the RWR/ESM receiver
of ascertain frequency-dividing numbers,there exists the optimal frequency-divi
ding measure in specific environment to minimize the overlapping pulses of RW
R/ESM receiver. |
