Spaceborne Synthetic Aperture Radar (SAR) Systems:State of the Art and Future Developments

摘要

This paper first summarizes the state of thernart in spaceborne SAR systems and applications. Thernsecond part of this paper gives an overview of newrnconcepts, techniques and technologies for future SARrnsystems, allowing an increase of flexibility in the SARrnoperation mode as well as a reduction in the overall systemrncosts. Several innovative concepts and technologies as biandrnmulti-static configurations, parasitic SAR, sparsernaperture systems and digital beamforming will play anrnimportant role for future spaceborne SAR constellations.
