| Abstract: | Six typical SAR satellites are researched,which either have been launched successfully since 2007 or are being manufactured. The concerned system technologies, such as orbit and revisit period characteristics, satellite configuration, power system, control system and data transmission system, are contrasted and analyzed. Development trends of overseas SAR satellites are summarized. Suggestions on development of our SAR satellite system technologies are put forward. |
