Spherical Geometry Algorithm for Space-borne Synthetic Aperture Radar Imaging
Xinhua Mao
Higher spatial resolution and larger imaging scene are always the goals pursued by advanced space-borne SAR system.High resolution and wide swath SAR imaging can provide more infor…
Knowledge-aided Two-dimensional Autofocus for Spotlight SAR Filtered Backprojection Imagery
Xinhua Mao, Lan Ding, Yudong Zhang +2
Filtered backprojection (FBP) algorithm is a popular choice for complicated trajectory SAR image formation processing due to its inherent nonlinear motion compensation capability.…
SAR Imaging of Moving Target based on Knowledge-aided Two-dimensional Autofocus
Xinhua Mao
Due to uncertainty on target's motion, the range cell migration (RCM) and azimuth phase error (APE) of moving targets can't be completely compensated in synthetic aperture radar (S…
Knowledge-aided Two-dimensional Autofocus for Spotlight SAR Polar Format Imagery
Xinhua Mao
Conventional two-dimensional (2-D) autofocus algorithms blindly estimate the phase error in the sense that they do not exploit any a priori information on the structure of the 2-D…
Autofocus Correction of Azimuth Phase Error and Residual Range Cell Migration in Spotlight SAR Polar Format Imagery
Xinhua Mao, Daiyin Zhu, Zhaoda Zhu
Synthetic aperture radar (SAR) images are often blurred by phase perturbations induced by uncompensated sensor motion and /or unknown propagation effects caused by turbulent media.…
