Text Size: A A A
1. General introduction
After years of construction and development, Institute of Electronics has become China's important R&D base of aerospace ground processing system and applied system. Four research directions have taken shape, including advanced sensor processing and simulation of satellite-terrestrial integration, multi-sensor data processing technology, microwave radiometric calibration technology, and spatial information applied system. The institute is domestically leading in such techniques as large-scale remote-sensing satellite ground processing system, applied system and SAR calibration. In order to research deep into this field, in 2009 the Key Laboratory of CAS Spatial Information Processing and Applied System was established on the basis of Institute of Electronics.
In recent years, a number of innovation achievements have been achieved, such as the construction of aerospace ground processing system and applied system, the construction of microwave radiation calibration field, novel remote sensing data processing with high accuracy which is represented by SAR, radiometric calibration and information extraction, etc. A more complete technical system of space remote sensing data reception, recording, processing and application has been formed. The institute has undertaken a number of national key projects and pre-research projects, and has won various awards including the first-class and second-class prizes of National Scientific and Technical Progress, and the first-class prize of the National Defense Science and Technology.
