UT信号的数字译码

Digital Decoding Methods of UT Signal

根据ＵＴ信号的特征，从时域和频域角度提出了两种数字译码方法。在时域分析法中，主要介绍了数字鉴频的指导思想和基本步骤；在频谱分析法中，重点阐述了隐谱线的确定条件和原理。两种分析方法均给出了仿真实例。

According to the characteristics of UT signal,this paper puts forward two ways of digital decoding:Time Domain Analysis and Frequency Domain Analysis.With the TDA method,this paper mainly introduces the principle and basic steps of digital frequency discrimination.With the FDA method,this paper emphasizes the specific conditions and principle of hidden spectrums.Simulated examples are given for both methods.
