本文建立了时差定位系统中直方留统计脉冲配对的信号互相关数学模型，将该模型应用于实际辐射源信号的脉冲配对，分析了直方图统计过程中伪峰值产生的原因，进一步指出了去除伪峰值实行脉冲配对及信号分选的途径．
In this paper, a mathematic model of signal correlation of histogram-dependent statistical pulse pairing in time-difference positioning system is established. The model is applied to the pulse pairing of the actual radiation source signal. The reason of pseudo-peak generation in histogram analysis is analyzed. Peak implementation of pulse matching and signal sorting approach.
