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

ScanSAR Radiometric Correction and Analysis of GaoFen-3
2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019GaoFen-3(GF-3) is China's first multi-mode c-band radar imaging satellite launched on August 10, 2016. In order to meet the requirements for global ocean observing and wave detection, three wide swath modes were designed using Scan-beam synthetic aperture radar (ScanSAR) imaging mode, which are narrow scan, wide scan and global observation.

Polarimetric Channel Misregistration Evaluation for the GaoFen-3 QPSI Mode
IEEE Geoscience and Remote Sensing Letters, 2019This letter presents two main contributions to the data quality assessment of China’s new GaoFen-3 radar satellite. First, we observed a half-pixel misregistration between the horizontal (H) and vertical (V) transmitting channels in the azimuth direction.

Land Cover Semantic Segmentation of High-Resolution Gaofen-3 SAR Image
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Land cover classification with SAR images mainly focuses on the utilization of fully polarimetric SAR (PolSAR) images. This paper explores the potential of semantic segmentation of high-resolution single polarimetric (single-pol) SAR and PolSAR images, in particular tailored for the Gaofen-3 (GF-3) sensor. First of all, a unified SAR data preprocessing
