基于时延估计法的自然伽玛能谱自动稳谱

传统的软件稳谱方法基于谱漂为线性漂移的假设,只利用一个主峰峰位进行校正,论文将时延估计中的相关法应用到软件稳谱,通过构造标准特征谱峰,与实际光滑后的谱峰进行相关计算寻找漂移道数。实例证明了该方法对于非线性谱漂校正性优于传统方法。

Spectrum-stabilizing Technique of Natural Gamma Energy Spectrum Based on Time Delay Estimation

In computer software spectrum-stabilizing aspect,the traditional method is based on the supposition that drifting of spectrum is linear.It uses a main peak position to adjust,but not to use other data effectively.The paper applied the relative method of time delay estimation to spectrum-stabilizing.By structuring standard characteristic spectrum peak,it carries on correlation calculation between standard characteristic spectrum peak and actual sliding spectrum peak to get the drifting number.Instance verified that the method surpasses the conventional method at the adjustment of nonlinear spectrum floats.
