Paper Abstract

Based on the extended fractional Fourier transform, we propose a zone-processing joint extended fractional Fourier transform correlator. With the zone-processing technique, first, the high- and low-frequency zone can be obtained from high- and low-brightness joint extended fractional Fourier transform power spectra, respectively. Second, they are combined into new power spectra, so it can preferably include high- and low-frequency information simultaneously. The experiment results demonstrate that this processing technique can largely improve correlation performance.
