摘　　要：本文针对密集信号分选这一难题，提出了一种新颖的方法：平面变换技术．在定义一种累积变换的数学公式的基础上，分析了各种脉冲信号的累积变换波形，进而找出一种实现该公式的极其简单的方法：将密集视频脉冲信号分段截取并逐行在平面上显示，通过平面显示宽度的变换，可以看到平面上代表各种不同信号的特征曲线，每种特征曲线是该种信号“调制”波形剔除其相应平均值后，再作累积变换而得到的累积特征曲线．从而可以分选出这些信号．In the dense signal environment, signal deinterleaving is a tedious problem by using traditional technique.This paper presents a new method──Plane Transformation. With this technique, the interleaved pulse trains were cut into many paxts and shown line by line as a plane fipe. By changing the width of the plane,various characteristic curves,representing the signals, can be seen. They are actually the result of the accumulation of the signal' s'modulation' substracting the corresponding average value, which can be used to deinterleave signals with less difficulty by other means.
