Abstract
This paper investigates the use of fractional Fourier transform (FrFT)-based Orthogonal Frequency Division Multiplexing for Synthetic Aperture Radar (SAR) imaging for single point target and extended target. The geometry of synthetic aperture radar using FrFT-based OFDM is presented with the developing algorithm to process the raw data to reconstruct the image of the target in the range and in the Azimuth direction. In the simulation results, single point target is assumed to be at the center of swath width to show the performance of this approach as well as the point spread function in the range and Azimuth direction. Extended target with the shape of tank is used to show the capability of this method in resolving extended target images.
