Design and Implementation of Data Processing and Control Module in Microwave Radiometer Based on Single Chip Computer

Data processing and control module is an important part of microwave radiometer,it has strict requirement with accuracy and stability.Its hardware structure,including data collection,antenna driving,controlling of antenna status,and serial communication are described.The upper computer software is implemented with C#.The 89C51 is the hardcore to control the antenna,collect and transmit data using AD976A.And communication of the system is held by use of the serial interface mode.The whole module has satisfied requirement of the system closely.
