摘要
最近提出了一种新的时频分布 ,在保持高时频分辨率的同时可抑制交叉项。本文从信号模糊域滤波的角度分析了该分布中核函数的设计方法与思路 ,并针对多分量线性调频信号用该分布进行了计算机仿真。
A new time frequency distribution is recently brought forward which can suppress the crossterms while having high time frequency resolution. This paper analyzes design of kernel function of the distribution from the point of filtering in signal ambiguity domain. Computer simulation is done by using this distribution respecting to multicomponent LFM signals. Results of computer simulation show validity of the distribution for suppressing the crossterms while holding high time frequency resolution.
