Since the first satellite-based SAR-Seasat-A launched in 1978,the major astronomical countries have launched many SAR satellites successively.For decades,the property of spaceborne SAR sensors has been increasing towards high resolution,multi-polarization,multi-mode and constellation.Germany and Italy have respectively deployed the satellite constellations of SAR-Lupe(5 satellites)and COSMO-Sky Med(4 satellites),which are used for military reconnaissance and civil applications.The ESA and Canada are actively developing SAR constellationmissions,and even some commercial companies have begun to develop small satellites SAR constellation.SAR constellation can improve the ability to observe the earth significantly,both through the formation of flight for double/multi-station,multi-angle or interference imaging,but also through the multi-satellites network greatly shorten the re-visit cycle to meet key areas of intensive observations.With SAR sensors and satellite platforms are increasing miniaturization and low cost,constellation network is becoming one of the main directions for the development of SAR ground observation.
