  • Abstract
    This paper presents a new acquisition capability of the ONERA RAMSES-NG SAR sensor consisting in circular imaging, and an associated experiment. Target recognition or area monitoring is tricky using classical SAR imaging because only a part of the object shape is visible. The backscattering is strongly dependant of the relative heading angle between the radar line of sight and the target. Then, circular imaging mode is very efficient to overcome this problem since 360° data are acquired in a single pass.
