摘要

所提出的方法允许定义核磁/四极共振(NMR/NQR)信号，并使用先前著名的信号参数来检测物质。检测该信号的结果就是对该物质的检测和鉴定。该方法基于连续小波变换后的模式信号与检测信号的卷积和互相干估计。对比有信号和无信号时互相干函数的阈值，可以看出检测物质信号的存在。

Signal processing in NMR/NQR detection on the base of pattern signal

The proposed method allows defining the nuclear magnetic/quadrupole resonance (NMR/NQR) signal with use the previously famous parameters of the signal for detecting substance. The result of the detection this signal is the detection and identification of the substance. The method is based on the convolution of the pattern signal and detecting signal after continuous wavelet transformation and estimation of mutual coherency. The comparison of the threshold values of the mutual coherency function wit and without signal shows the presence of the signal of detecting substance.
