摘要
Abstract
MeoSAR is the spaceborne SAR with orbit height between 3 000 km and 10 000 km.MeoSAR is a compromise between GeoSAR and LeoSAR for its powerful observation capability and less challenging technology difficulties.It is very promising for earth observation.Concepts and system design considerations of MeoSAR are investigated and some technology challenges are discussed.A range ambiguity suppression method based on antenna shaping and a high precision time-domain imaging algorithm are proposed.Moreover,the difficulties of antenna design and space environment adaptability are discussed.The investigation can be referenced for the MeoSAR system design and applications.关键词
