技术领域Technical Field
本发明涉及信号处理技术领域，尤其涉及一种堆积脉冲信号识别与成形方法、计算机程序产品及终端。The present invention relates to the field of signal processing technology, and in particular to a method for identifying and shaping a pile-up pulse signal, a computer program product and a terminal.
背景技术Background technique
在高计数率的环境中，相邻脉冲信号会出现部分重合的现象，称为堆积脉冲。堆积脉冲会影响信号幅度的提取与测量系统的能量分辨率。因此，堆积脉冲信号的识别与分解成形对提高测量系统性能具有积极的意义。In a high counting rate environment, adjacent pulse signals will partially overlap, which is called pile-up pulses. Pulse pile-up will affect the extraction of signal amplitude and the energy resolution of the measurement system. Therefore, the identification and decomposition of pile-up pulse signals has a positive significance for improving the performance of the measurement system.
传统解决堆积脉冲的方法是使用堆积拒绝电路，直接放弃堆积的脉冲信号， 然而此种方式会使得脉冲通过率下降，并增加了系统死时间。因此，对堆积脉冲识别与分解成形是十分必要的。目前常用堆积脉冲识别方法是根据成形信号是否含有多个峰值来判断是否存在堆积。这种方法比较方便，也不需要额外的运算资源，但是对于时间间隔较小（如ns级）的堆积脉冲，该方法存在堆积脉冲识别不理想的问题，如杨小艳等人提出的基于小波变换的双指数信号高斯脉冲成形算法研究中，给出了成形结果如图1所示，图1中（a）表示μs级输入信号，（b）表示高斯脉冲成形结果，（c）表示梯形脉冲成形结果，输入信号中三个方框框选位置为存在堆积脉冲，可以看出高斯脉冲成形（Gaussian Pulse Shaping）、梯形脉冲成形（Trapezoidal Pulse Shaping）对堆积脉冲的识别与分解成形效果均不理想。The traditional method to solve the pile-up pulse is to use a pile-up rejection circuit to directly abandon the piled-up pulse signal. However, this method will reduce the pulse pass rate and increase the system dead time. Therefore, it is very necessary to identify and decompose the pile-up pulse. At present, the commonly used pile-up pulse identification method is to judge whether there is a pile-up based on whether the formed signal contains multiple peaks. This method is more convenient and does not require additional computing resources. However, for pile-up pulses with a small time interval (such as ns level), this method has the problem of unsatisfactory pile-up pulse identification. For example, in the study of the Gaussian pulse shaping algorithm of double exponential signals based on wavelet transform proposed by Yang Xiaoyan et al., the shaping results are shown in Figure 1. In Figure 1, (a) represents the μs-level input signal, (b) represents the Gaussian pulse shaping result, and (c) represents the trapezoidal pulse shaping result. The three box-selected positions in the input signal are pile-up pulses. It can be seen that Gaussian pulse shaping (Gaussian Pulse Shaping) and trapezoidal pulse shaping (Trapezoidal Pulse Shaping) are not ideal for the identification and decomposition of pile-up pulses.
