Implementation of the Swept-frequency Filter's in Fractional Fourier Domain
Haoming Liu · Computer and Information Technology · 2007
On the basis of researching theories of fractional Fourier transforms area filtering,the working theories and system appearance of swept-frequency filter are pointed out.Seen from the emulation results separating LFM signal and Gauss white noise,the SNR is preferably improved after separating.Emulation results indicate that the swept-frequency filter in fractional Fourier transform can obtain better effect of separating filtration and interfere in the noise situation.
