heal.abstract	The performance and limitations of the Extended Chirp Scaling (ECS) algorithm and wavenumber domain Omega-K processing algorithm were analyzed and discussed. Additionally, modification of both algorithm were proposed, which optimize the respective algorithm for processing low frequency, wide-beam and wide-band SAR data. Despite of the inherent limitations of the given processing algorithms, a deterministic phase error known as the ""digital phase error"" due to digital signal processing characteristics was formulated and its effect to the processed Synthetic Aperture Radar (SAR) data was analytically described.	en
