A CSAR 3D Imaging Method Suitable for Edge Computation

open access: yesElectronics (Switzerland), 2023
Due to the large amount of CSAR echo data carried by UAVs, either the original echo data need to be transmitted to the ground for processing or post-processing must be implemented after the flight. Therefore, it is difficult to use edge computing power such as a UAV onboard computer to implement image processing.

GPU-Optimized Implementation for Accelerating CSAR Imaging

open access: yesElectronics (Switzerland)
The direct porting of the Range Migration Algorithm to GPUs for three-dimensional (3D) cylindrical synthetic aperture radar (CSAR) imaging faces difficulties in achieving real-time performance while the architecture and programming models of GPUs significantly differ from CPUs.

210Pb-based dating of recent sediments with the χ-mapping version of the Constant Sediment Accumulation Rate (CSAR) model

open access: yesJournal of Environmental Radioactivity, 2023
The 210Pb-based method aims at determining the absolute age of recent sediments on the centennial scale. A family of models assumes that at the sediment-water interface the flux of unsupported 210Pb ( 210Pbexc), F, relates to its initial activity ...

A Method of Subaperture Division in CSAR Imaging

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
This paper proposes an imaging algorithm with adaptive aperture energy division. This method is suitable for circular synthetic aperture radar (CSAR). The algorithm is an extension of the traditional CSAR polar format algorithm (PFA). Firstly, to avoid the loss of image detail information caused by the mismatch between the aperture size and the energy ...

Cryogenic Solar Absolute Radiometer (CSAR)

Metrologia, 1993
The Cryogenic Solar Absolute Radiometer (CSAR) is a new primary radiometric standard for use in space traceable to the International. System of Units (SI). CSAR will have the potential to measure the total irradiance of the Sun with an uncertainty of 0.01% and a resolution of 0.001%, more than a factor ten improvement over existing instruments.
