Passive SAR satellite constellation for near-persistent earth observation: Prospects and issues
Abstract
Over the last decades spaceborne synthetic aperture radar (SAR) has proved its capability as a remote sensing technique of great power and value. A number of precise SAR instruments (e.g., [1]-[4]) have been developed by space and defense agencies around the world and are being used today for a wide range of applications in wide-area land (e.g., [5]-[8]) and sea monitoring (such as [9]-[11]).
