Tomographic 3D reconstruction from airborne circular SAR [PDF]
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009 The study of data acquired over a circular trajectory has raised an increasing interest in the SAR community. Two main reasons summarize the interest in such geometry. First, sub-wavelength resolution can be achieved, as the targets in the spotted area are observed under a 360o aperture.

Polarimetric Decomposition With an Urban Area Descriptor for Compact Polarimetric SAR Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 The compact polarimetric (CP) synthetic aperture radar (SAR) can alleviate the drawbacks of the fully polarimetric (FP) SAR and provide more target information as compared to the conventional single polarimetric and dual polarimetric mode.

A GAN-based fast focusing method for circular SAR images. [PDF]
HeliyonCircular Synthetic Aperture Radar(CSAR) imaging is vulnerable to perturbations in the atmosphere and various other elements that can lead to position offset errors in the antenna's phase center as well as induce motion errors. Traditional phase compensation methods that operate in the time domain, such as Auto-regressive Back-projection (ARBP ...
