Abstract

In this paper, we introduce a new imaging algorithm for synthetic aperture radar raw-data. This is based on the most compact representation of a chirp signal using the fractional Fourier transform. Pulse compression in range, azimuth and range cell migration correction are obtained only from the rawdata, unlike methods documented in the literature, there is no need to enter radar operating parameters [1] or make any kind of inference from those [2, 3].
