Analysis of a New Time-frequency Distribution for Suppressing the Crossterms

从信号模糊域滤波的角度分析了最近提出的一种新的高时 频分辨率抑制交叉项的时 频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。仿真结果证明了该分布在抑制交叉项并保持较高时 频分辨率方面的有效性。

Analysis of a New Timefrequency Distribution for Suppressing the rossterms Abstract:The method of the kernel design of the recently brought forward timefrequency distribution which can solve high timefrequency resolution and suppress the crossterms from the point of filtering in the signals ambiguity domain is analyzed in this paper.The computer simulation is done by using the distribution respecting to multicomponent LFM signals.The results of computer simulation show the validity of the distribution for suppressing the crossterms and holding high timefrequency resolution.
