视频分析方法中的平滑伪Wigner-Ville分布等效于对WVD的结果在时域和频域分别进行一次平滑滤波，有效抑制交叉干扰。-Video analysis methods smoothed pseudo Wigner-Ville distribution is equivalent to the result of the WVD smoothing once were in the time domain and frequency domain, inhibit cross-interfere

时频分析的Wigner-Ville分布方法是非平稳信号分析的有力工具，交叉项的存在在一定程度上影响其使用。-Powerful tool Wigner-Ville distribution method for time-frequency analysis of non-stationary signal analysis, the existence of cross terms to some extent affect its use.
