Radar backscatter analysis using fractional Fourier transform

This paper focuses on analyzing radar backscatter returns using the fractional Fourier transform. This study is motivated by two factors: first, to examine the radar backscatter mechanism of standard small targets; and second, to extract pertinent scattering features that can be used in target recognition. Radar returns have been examined using time-frequency analysis techniques, particularly those targets with dispersive scattering behavior. The FrFT scattering analysis scheme is tested using real radar signatures of commercial aircraft recorded in the UHF range.
