The detection of marine environment elements include surface temperature,salinity,ice thickness,significant wave height etc.Usually,marine environment elements are detected by microwave radiometer.High resolution and sensitivity radiometer normally has wide signal bandwidth,multi-channel,hybrid system for acquisition,correlation and inversion processing with distributed and classification strategy.According to the project requirements,the design and realization of detector with multi-channel acquisition and processing unit for marine environment elements are highlighted.The test and verification are combined with radiometer system and acquisition and processing unit.The results show that the designed multi-channel acquisition and processing unit can correctly acquire and process the broadband signal at 400 MHz,assist the digital correlator to realize the interference processing,and complete the extraction of inversion imaging parameters.

To adapt the stand-alone testing and system testing for different staellites at the same time,distributed software architecture was introduced into satellite ground test. A generalized software platform was set up with main software ,database and client program based on 1553B.The design of the platform introuced the concept of hardware interface standardization,function modulization and configuration. Firstly, hardware construction and software design of the platform were shown. Then, requirement analysis and software modeling of the platform were done. At last, generalized software platform was realized. The generalized software platform based on 1553B for satellite ground test was verified to have strong commonality and full coverage of tests, which can be better at meeting the test demand of multiple equipments in satellite system.
