Noncoherent Imaging Experiments of Circular SAR

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Circular synthetic aperture radar (CSAR) observes the scene by 360 degrees, the characteristics of targets from different aspects can be obtained. The noncoherent imaging is more popular since more textural features and lower speckle noise can be acquired.

SAR Parametric Imaging for Circular-Plate Target

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The traditional synthetic aperture radar (SAR) is an active acquisition instrument that generates radiation and captures signals backscattered from the illuminated scene. However, when the phases of each reflection path are highly similar, the received echoes may sum in a destructive way.

Circular SAR GMTI

SPIE Proceedings, 2014
We describe techniques for improving ground moving target indication (GMTI) performance in multi-channel synthetic aperture radar (SAR) systems. Our approach employs a combination of moving reference processing (MRP) to compensate for defocus of moving target SAR responses and space-time adaptive processing (STAP) to mitigate the effects of strong ...

Multiple-input multiple-output circular SAR

2014 15th International Radar Symposium (IRS), 2014
Interest on circular and multicircular SAR acquisitions has been increased in the past few years due to the inherent potentials they provide, e.g., full 3-D reconstruction and subwavelength resolution. However, one main limitation is the size of the spotlighted region, which is basically defined by the range ambiguities, the pulse repetition frequency (
