摘要：
The possibility of identifying close signals based on the method of Wigner cross distribution (WCD) moments is analyzed. The WCD moments are regarded as primary descriptors. Formulas that enable one to assess the sensitivity of WCD moments to variations of signal parameters, determine signal distinction parameters, and identify signals are derived. Calculation results are presented for two types of radio signals. The efficiency of identification is verified experimentally for the WCD section coinciding with the cross-correlation function.
