密集电磁环境下脉冲信息的丢失概率

Research on Probability of Pulse Information Missing Under the Dense Electromagnetic Environment

密集电磁环境下,电子战侦察设备常常面临同时接收多部雷达的信号,而这些脉冲信号可能相互重叠,导致脉冲信息丢失的问题。详尽分析了脉冲丢失概率和脉冲信息丢失概率,并给出了它们的比较结果。研究结果为正确设计接收机和后续的信号处理机提供了良好的理论基础。

Usually the ESM equipments face the problem of receiving signals from multiple sets of radar under dense electromagnetic environment, and those pulse signals may be overlapped so that it may result in pulse information missing. Deliberate analysis is provided on probability of pulse missing and probability of pulse information missing as well as comparison result. Therefore good theoretical basis is placed by the study result on optimal design of receiver and the signal processor.
