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.
