摘要
跳频信号是典型的非平稳信号,需采用非平稳信号处理方法进行分析.介绍了跳频信号的模型以及Wigner-Ville分布、伪Wigner-Ville分布的离散化实现过程,可得到跳频信号的有关参数,进行了计算机仿真.结果表明Wigner-Ville分布和伪Wigner-Ville分布均可对跳频信号进行分析,伪Wigner-Ville分布可以抑制交叉项的影响,这种分析方法是有效的、合理的.
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.
