【Abstract】 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.更多还原
