一种新的减少交叉项的时频分布分析

Analysis of a New Time-frequency Distribution of Suppressing the Cross-terms

针对时频分布中的交叉项问题,引入了重排理论,结合魏格纳———霍夫变换,提出了一种新的减少交叉项的方法———重排魏格纳—霍夫变换,实验验证该方法在抑制交叉项和提高时频分布检测性能方面的有效性。

The method of the Reassignment for suppressing the cross - terms is introduced in this paper. With this method and WHT, a new Time - frequency distribution - RWHT is proposed. The results of computer simulation show and verify the validity of the distribution in suppressing the cross - terms and improving the detection capability of Time - frequency Distribution.
