Fractional Fourier transform
4.0
Matlab calculates fractional Fourier transform. The LFM signal is denoised by FRFT + filter and then anti FRFT to get the de-noising signal. Routine integrity, there are running results. LFM has great application in sonar and radar. The FRFT is a fractional Fourier transform, and the corresponding parameters are obtained by doing the p-order transform, which also has a good effect on LFM parameter estimation.
