摘　　要：随着现代战场电磁环境日趋复杂,辐射源不断增多,脉冲丢失成为机载RWR/ESM系统的一个严重问题。在机载RWR/ESM系统各射频前端通道发生脉冲交叠的基础上,分析了机载RWR/ESM系统测向环节在象限判别过程中的脉冲丢失概率,推导出脉冲象限判别概率的工程估算公式。最后通过仿真验证了机载RWR/ESM系统象限判别过程中,脉冲的象限鉴别正确概率与其输入脉冲密度之间的关系。With the complex’s development of modern battlefield electromagnetic environment, radiation sources growing, pulse missing become one of serious problems in airborne RWR(Radar Warning Receiver)/ESM (Electric Support Measure) systems.Based on pulse overlapping in RF front channels of airborne RWR/ESM system, pulse missing probability is analysed in quadrant distinguish, which is one of direction finding processes in airborne RWR/ESM system, engineering estimation formula is inferred of pulse quadrant distinguish probability, at last, the relationship is verified by simulations between pulse quadrant distinguish probability and input-pulses density.
