Preliminary Coherence Assessment of Gaofen-3 SAR Data
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Gaofen-3 (GF-3) is the only in-orbit civilian SAR satellite of China. The satellite is specially designed for ocean observation. The coherence is not exclusively considered during satellite designing phase. In this paper, we conduct the preliminary coherence assessment of GF-3 SAR data. Decoherence sources of GF-3 consists of seven components. Baseline

A Spaceborne SAR Calibration Simulator Based on Gaofen-3 Data
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Synthetic Aperture Radar (SAR) is widely used in remote sensing field, especially for the acquisition of quantitative information about the earth’s environment. Calibration processing is critical for SAR image quantitative applications. This paper proposes a spaceborne SAR calibration simulator to describe the calibration process.

Comparison of Gaofen-3 and Radarsat-2 Data for Polarimetric Sar Image Classification
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018On 10 August 2016 China launched the GF-3, its first C-band polarimetric synthetic aperture radar (SAR) satellite, which was put into operation at the end of January, 2017. The GF-3 polarimetric SAR has many advantages such as high resolution and multi-polarization imaging capabilities.

Detection of Supraglacial Lakes using Gaofen-3 data and Advanced Attention U-Net
Detecting supraglacial lakes is becoming increasingly crucial in the rising of global warming. Serving as vital indicators of glacier surface runoff storage and loss, these lakes provide significant insights to the understanding of glacier mass balance and global sea-level changes. Synthetic Aperture Radar (SAR) images have been used ...Di Jiang, Shiyi Li, Irena Hajnsek
