Abstract: A new method was proposed to suppress the cross-terms of Wigner-Ville distribution. First，the cross-terms were detected between the Wigner-Ville and the Margenau-Hill distributions based on the geometry difference of cross-terms representation，then a mask filter was designed to eliminate them. Finally，the results of simulation indicate that this technique is feasible.

摘要： 提出了一种可行的检测Wigner-Ville分布交叉项并将其抑制掉的新方法。Cohen类时频分布之一的Margenau-Hill分布同Wigner-Ville分布一样，拥有众多的优良特性，但它和后者交叉项在时频面上的分布却有天壤之别。于是，根据两种分布交叉项在时频面的特点将交叉项检测出来，进而设计二维遮蔽滤波器将交叉项移除。最后的仿真表明了该方法的可行性。
