Abstract

Abstract

A new kind of bilinear time-frequency distribution-adaptive Gaussian-kernel distribution (AGD) is proposed according to multi-component linear frequency-modulated (LFM) signals, and a new efficient kernel estimation method is presented. With the AGD as an example, the influences of the adaptive kernel to the signalterms and crossterms are discussed in detail, which from another point of view indicates its advantages over the fixed kernel. Finally, a common adaptive kernel design method based on ambiguity domain for LFM signals is generalized. Computer simulations confirm the performance improvement of AGD and its corresponding analysis.
