Study on Geosynchronous Circular SAR
Leida xuebao, 2015 The concept of Geosynchronous Circular SAR (Geo-CSAR) is introduced in this paper. With the design of the geosynchronous orbit parameters, a near-circular satellite sub-track could be formed to enable the staring imaging mode, which supports the advanced

Three-dimensional Reconstruction Method Study Based on Interferometric Circular SAR
Leida xuebao, 2016 Circular Synthetic Aperture Radar (CSAR) can acquire targets’ scattering information in all directions by a 360° observation, but a single-track CSAR cannot efficiently obtain height scattering information for a strong directive scatter.

Resolution Equation for SAR Systems Synthesizing Circular Aperture
IEEE AccessThe resolution of a synthetic aperture radar (SAR) system depends not only on the operating frequency range of a radar but also on the geometry. A radar system operating at MHz frequencies facilitates SAR resolution to the meter (m) level with a linear ...

Analysis of Azimuthal Variations Using Multi-Aperture Polarimetric Entropy with Circular SAR Images
Remote Sensing, 2018 In conventional synthetic aperture radar (SAR), sensors with a fixed look angle are assumed, and the scattering properties are considered as invariant in the azimuth.

Circular SAR imaging algorithm based on polar format algorithm for moving target
The Journal of Engineering, 2019 For stationary targets, circular synthetic aperture radar (CSAR) imaging has tended to be mature and perfect. However, for moving targets, due to the long synthetic aperture and the variation of slant plane with the observation angle, the motion ...

Analysis of the Azimuth Ambiguity and Imaging Area Restriction for Circular SAR Based on the Back-Projection Algorithm. [PDF]
Sensors (Basel), 2019 Circular synthetic aperture radar (CSAR) has a 360° observation capability on the central observation scenario. A typical way to process CSAR imaging is to cut data into small sub-apertures because most targets are only coherent at a very small ...
