Abstract

We present a new 2D squint mode Synthetic Aperture Radar (SAR) processor. It is based on the analytical evaluation of the SAR system transfer function via the stationary phase method. In particular we will underline the space-variance nature of the system function. In our processing approach, this space-variance will be taken into account by evaluating the 2D SAR raw data spectrum on a deformed grid; this is possible by using a non standard Fourier transform. Availability of the 2D spectrum on a deformed grid and of the 'exact' expression of the system transfer function allows the high precision processing of the raw data for squinted geometries.
