针对核信号在时间、幅度上的随机性，探讨模拟核信号的发生装置。采用基于混合同余法、舍选控制法的蒙特卡洛方法在MATLAB中产生任意分布随机波形数据。高速FPGA通过串口接收上位机发出的控制命令和波形数据并存储在双口RAM，利用控制命令快速实现DDS技术和外部DAC，从而实现具有统计特性的核信号。实验结果表明所设计的仿核信号发生器能够有效模拟真实核信号的发生，对数字化核测量系统研究工作有重要意义。

Based on randomness of kernel signal in amplitude and time , simulation of the kernel signal generator is discussed .Using mixed congruence method , and selected method , such as the Monte Carlo method , random waveform data was produced in MATLAB .High-speed FPGA stored in the dual port RAM via a serial port re-ceives control commands from the upper machine and waveform data , using the control command to implement DDS technology and the external DAC quickly , so as to realize the statistical kernel signal .The measured re-sults show the effectiveness of the design ,and it is important for the research of Digital measurement system a-bout nuclear .
