摘要
为解决基于PC机平台、高达1 GHz采样率下的相关函数计算的实时性需求, 针对中子脉冲序列核信号本身所具有的结构特点, 设计了高速、实时的相关函数计算方法, 实现了采样率为1 GHz的中子脉冲序列核信号的实时相关函数计算。性能测试结果表明, 算法达到了对中子脉冲序列核信号进行相关计算的时间在1 h以内的实时性要求, 使得铀部件质量丰度的实时检测成为可能。
Abstract
The real-time algorithm of correlation calculation is presented for neutron pulse series up to 1 GHz sampling rates based on PC. The method is proposed based on the special structure of the series. Simulation demonstrates that the calculation time of the proposed correlation function algorithm is less than 1 h, the algorithm meets the demand of real-time correlation calculation, which make it possible to detect the quality and abundance of uranium components in real time.
