摘要：
Frequency-hopping (FH) signal that is typical non-stationary signal needs to be analyzed by processing methods of non-stationary signal. The FH signal model was introduced, and the discrete processing of Wigner-Ville distribution (WVD) and pseudo Wigner-Ville distribution (PWVD) was recited. The relative parameters could be obtained. The WVD and PWVD analysis process of FH signal were simulated by computer. The results show that the FH signal can be analyzed by the WVD and PWVD methods. The PWVD method can reduce the influence of WVD cross-terms, and it is effective and feasible.
