Research on the Processing Method of Digital Nuclear Signal Filtering Based on MATLAB

在数字核信号的处理中,为获取更好的能量分辨率等性能指标,需要对核信号数字滤波成形处理方法进行研究。基于数值递推方法分别建立了高斯成形和梯形(三角形)成形模型,然后搭建一套基于MATLAB的数字核信号滤波成形处理平台,实现仿真核信号与实际采样核信号的滤波成形处理,分析各滤波成形方案的特点以及不同成形参数对滤波效果的影响,为最优化数字滤波成形方案的选择、最佳滤波成形参数的选取提供设计指导与技术支持。

In the processing of digital nuclear signals,the better energy resolution and other performance can be obtained by improving the digital filtering method of nuclear signals. Based on the numerical recursion method,the forming models of Gauss forming and trapezoid（triangle） are established respectively,and then a digital nuclear signal processing platform based on MATLAB is built. Depending on this platform,the processing of the simulation nuclear signal and the actual sampling nuclear signal is completed,and the characteristics of the various forming schemes and the influence of different forming parameters on the filtering effect are also analyzed,these provide a design guidance and technical support for the optimal digital forming scheme and the best shaping parameters selection.
