Abstract
The Gaofen-3 (GF-3) data processor was developed as a workstation-based GF-3 synthetic aperture radar (SAR) data processing system. The processor consists of two vital subsystems of the GF-3 ground segment, which are referred to as data ingesting subsystem (DIS) and product generation subsystem (PGS). The primary purpose of DIS is to record and catalogue GF-3 raw data with a transferring format, and PGS is to produce slant range or geocoded imagery from the signal data. This paper presents a brief introduction of the GF-3 data processor, including descriptions of the system architecture, the processing algorithms and its output format.
Highlights
Gaofen-3 (GF-3) is a Chinese spacecraft carrying a C-band synthetic aperture radar (SAR) (5.4 GHz), which was launched in August 2016, from Taiyuan (Shanxi Province, China)
(HJ-1C) SAR [3], GF-3 SAR can operate at high resolution spotlight mode, dual-receive stripmap mode, dual polarization stripmap or scanSAR mode, and quad polarization stripmap mode, which can be separated into 12 observing modes by different resolution and swath [1]
The GF-3 data processor (GF3DP) is the crucial part within the whole GF-3 ground segment, and it was developed by Institute of Electronics, Chinese Academy of Sciences (IECAS) as a promotion to the original IECAS SAR data processing system, which supports the processing of various data products for other preceding SAR satellites in China
Summary
Gaofen-3 (GF-3) is a Chinese spacecraft carrying a C-band SAR (5.4 GHz), which was launched in August 2016, from Taiyuan (Shanxi Province, China). The GF3DP consists of two subsystems of the GF-3 ground segment, which are referred to as the data ingesting subsystem (DIS) and the product generation subsystem (PGS) physically located at China Center for Resources Satellite Data and Application. This paper will give a brief introduction of the architecture, the processing algorithms and the output format of GF3DP Typical processing results both at the commissioning phase and after GF-3 satellite has been in operational application will be provided in the later section. Typical processing results both at the commissioning phase and after GF-3. 18, 835 satellite been in operational application will be provided in the later section
