DOI: 10.1109/lgrs.2017.2671879
Abstract: In bistatic forward-looking synthetic aperture radar (BFSAR), conventional autofocus algorithms cannot estimate the phase errors accurately when the range walk is compensated in the azimuthal time domain. This problem stems from the influence of the… read more here.

DOI: 10.1109/tgrs.2022.3162230
Abstract: Fast factorized back-projection (FFBP) has significant advantages for bistatic forward-looking synthetic aperture radar (BFSAR) imaging with arbitrary geometry and complex configuration. Conventional FFBP is generally based on the polar coordinate system (PCS) for recursive processing;… read more here.

DOI: 10.1109/tgrs.2022.3228803
Abstract: In high-maneuverability bistatic forward-looking synthetic aperture radar (HMBF-SAR) imaging, the acceleration leads to an increased residual range curve and a deepened 2-D spatial variance of Doppler parameters, which cannot be processed by the traditional algorithms.… read more here.
