This paper extends the processing capability of the wide angle synthetic aperture radar (WASAR) algorithm (1992) to synthetic aperture radar (SAR) data acquired with the radar beam directed with an offset angle (squint angle) from the zero Doppler direction. The key point of this work is the analytical evaluation of the system transfer function for the squinted geometry via the stationary phase method. The range dependence of this new transfer function is compensated in two steps: a phase multiplication and a modified version of the basic fractional Fourier transform (FT). The performance of the extended algorithm is demonstrated by experiments with real and simulated data.
