摘要

立足于信号的参数化模型—多分量多项式相位信号

提出了一种新的时频分布并给出了其构造方法.该方法根据待分析的瞬时相关函数中自项分量及交叉项分量相位的不同特点

采用相位匹配的方法估计各信号分量的瞬时频率.所构造的时频分布不仅具有理想的频率聚集性

而且实现了绝大多数交叉项分量的有效抑制

有效克服了多线性时频分析方法的局限性.

Abstract

Based on parametric model of signal-multicomponent polynomial phase signal

a novel time frequency kernel is presented.It estimates the instantaneous frequency of each signal component by matched-phase transform

according to different features of phases between the autoterms and crossterms of the instantaneous correlation function of the signal under analysis.The novel time frequency kernel constructed not only shows ideal frequency concentration

but also suffers from few or no crossterms.So

compared with the existing multilinear time-frequency representations

it has advantages in exposing inner characteristics of signals.
