Abstract


Spaceborne radar altimeter sea surface height, significant wave height and wind speed measurements, the results can be applied to these data further inversion of marine geophysics , ocean dynamics , ocean climate and environment and sea ice monitoring . Introduced a new generation of high-precision radar altimeter synthetic aperture technology to traditional radar altimeter , and improve the measurement precision and spatial resolution . The high-precision radar altimeter , depending on the measurement objectives , the two modes of operation : SAR mode and low-resolution mode , these two modes of operation corresponding to control the timing associated with microwave switch timing . High-precision altimeter these two work mode switching , require other functions (such as satellite - platform communication functions ) unit of uninterrupted work , which requires radar altimeter control system with dynamic reconfiguration capability . In order to achieve these goals , the study and preliminary design Altimeter control system for self-reconfigurable FPGA-based reconfigurable technology . The FPGA reconfigurable technology , at the same time to explore the high - performance reconfigurable radar altimeter control system , including the following aspects : ( 1 ) the status and application of reconfigurable technology analysis explores FPGA reconfigurable based on research the refactoring implementation of three dynamic part , focusing on the implementation details of the method based on modular reconfigurable . (2 ) in the analysis of different configurations of the reconstructed data control method based on the focus on the technical details of the self-reconfigurable include building FPGA - based SOPC system the the modular reconstruction method EAPR processes and the merger of the two proposed operational self-reconfigurable system design process to solve the key issues in the software design . ( 3) in FPGA reconfigurable technology research based on the design of the self-reconfigurable systems altimeter control unit for dynamic module completed altimeter control unit logic , different bus macro IP and the preparation of self-reconfigurable software . Finally, the experimental verification , validation results show that the use of self-reconfigurable technology can carry out high-precision radar altimeter control system design .
