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.
高分三号（GF-3）数据处理器是作为基于工作站的GF-3合成孔径雷达（SAR）数据处理系统而开发的。该处理器由GF-3地面段的两个重要子系统组成，分别称为数据摄取子系统（DIS）和产品生成子系统（PGS）。DIS的主要目的是以传输格式记录和编目GF-3原始数据，而PGS则是从信号数据中生成斜距或地理编码图像。本文简要介绍了GF-3数据处理器，包括系统架构、处理算法及其输出格式的描述。
