| Abstract: | According to the characteristics of chirp signa] in ambiguity domain, this paper of-fers linear kernel time-frequency representation method. This method has high capability in im-proving precision,removing the cross-terms and restraining noises. Theoretical analysis and exper-imental results all prove the validity of this method. |
