Airborne Sar Imaging Based On Hla Deal With The Development Of Simulation Federates

The distributed simulation of Synthetic Aperture Radar (SAR) system based on High Level Architecture (HLA) can simulate the SAR working environment, the process of the SAR system dynamic work and the image result. The foundation of SAR simulation system offers an important method and tool for the system design, performance analysis, system evaluation and optimization of SAR.This dissertation analyzes the RD Algorithm and CS Algorithm which adapt for the airborne SAR, and designes the Data Arrange Federate and Signal Processing Federate of the distributed simulation Federation of SAR system based on HLA. The main content of this dissertation is as follows:1. This dissertation analyzes the theory of high-resolution airborne SAR imaging, imaging model and imaging processing. Then RD Algorithm and CS Algorithm are researched, simulated based on airborne stripmap SAR, Then their performance are compared and analysed.2. This dissertation researches the techno-frame of HLA, including the rule, the interface specification, Object Model Template and Run-time Infrastructure, Then the model, simulation frame and simulation flow of the distributed simulation of airborne SAR system based on HLA are also introduced in detail.3. According to the frame of airborne SAR simulation system based on HLA, designing the Data Arrange Federate and Signal Processing Federate including the RD Algorithm and CS Algorithm. In the process of designing, we apply multi-core and multi-thread technology, optimize the arithmetic flow, and the resultful memory management to improve the emulational performance of SAR system. Finally give the test project and the test result.4. Adding the designed Federate into the simulation Federation, and researching the simulation test. Then comparing the RD and CS Algorithm by the result of system test, and the result is analysed.
