Multi-aspect SAR-GMTI and Experimental Research on Gaofen-3 SAR Modes
doi: 10.12000/JR20021
More Information-
Abstract
Multi-aspect SAR is a new SAR mode that has two advantages, i.e., long-term observations and a large synthetic-aperture azimuth angle. Previous studies have reported that these unique advantages enable even single-channel systems to have a relatively strong capability for detecting moving targets, i.e., multi-aspect SAR expands and improves the moving-target-related capabilities of the earlier SAR satellite system without increasing its complexity. As such, multi-aspect SAR-GMTI has become a trending topic for research. After reviewing the recent progress and research basis of multi-aspect SAR-GMTI, in this paper, we present our research on the Gaofen-3 SAR, which includes: moving-target detection methods that use the staring spotlight mode, dual-channels GMTI mode, and the dual-channel spotlight GMTI mode. With the results obtained by this research, we hope to establish a basis for the engineering implementation of current and future spaceborne single-channel SAR-GMTI modes and the design of a future spaceborne multi-aspect SAR mode capable of retrieving time-series and dynamic scene information. -
