Paper Abstract

This paper proposes a new approach for high resolution SAR processing which is suitable for real-time processing of highly squinted data. The proposed approach does not use any interpolation and minimizes the storage requirement in the processing. The basic idea is to perform a 1D range and azimuth processing with no range cell migration correction. The defocused impulse response function (IRF) is then correlated with a small 2D kernel (typically 32 X 32 points) which deconvolves the amplitude and phase errors. Several simulation results using the parameters of the E-SAR system of DLR are presented to demonstrate the validity of the new approach.
