Title: On-board Signal and Information Processing for Remote Sensing Satellites
Abstract: With the development of remote sensing technology, the Earth observation satellites have the characteristics of high resolution, wide coverage and multi-satellite network. So the acquired data grows geometrically, which brings severe challenges to the transmission, storage and processing of satellite data. On-board real-time processing technology is an effective means to solve these problems. Based on this technology, the data processing is completed within the satellite, such as interest region extraction, target detection and recognition, etc. Then the processing results can be directly transmitted to the users through broadcast downlink. The information acquisition delay can be reduced from hours to minutes. Because of the on-board processing technology, the application efficiency will be greatly improved, such as in the situations of emergency, disaster reduction and national security.
This Keynote firstly expounds the development of Earth observation remote sensing satellites. And then, the significance and the technology development of the on-board real-time processing are introduced. Secondly, the technology difficulties and solving methods of on-board processing for optical or SAR payload are discussed. Finally, the development of the technology is prospected.
