摘　　要：随着空中交通流量快速增长,空中飞行目标密度不断增大,航管应答信号出现重叠现象成为常态,严重影响二次监视雷达(SSR)的情报质量。文中讨论了重叠应答信号的特征,归纳梳理出解重叠信号的主要方法。基于应答脉冲译码条件,分析了重叠应答信号的正确译码概率,推导出其一般规律,同时在系统层面上进一步提出了优化解重叠信号译码正确率的策略,实现了航管目标信息的准确获取,为SSR情报信息质量提供了技术保障。With the rapid growth of air traffic flow and the increasing density of air flying targets,the overlap of secondary surveillance radar(SSR)replies have become a normal phenomenon,the intelligence quality of SSR is seriously affected.The characteristics of overlapping replies are discussed,the main methods of de-overlapping replies are summarized.Based on the decoding conditions of reply pulses,the correct decoding probability of overlapping replies are analyzed,and its general rule is deduced.At the same time,the strategy of improving the decoding accuracy of overlapping replies are further proposed at the system level,and the accurate acquisition of air traffic control target information is realized,which provides a technical guarantee for the intelligence information quality of SSR.
