Sar Jamming Hla-based Simulation Technology Research

A computer simulation system for Synthetic Aperture Radar (SAR) is an important method to design and performance analysis a SAR system. On the other hand, the distributed simulation system based on High Level Architecture (HLA), which has been established as an open and international IEEE standard, has a good performance on reusability and interoperability. In addition, the necessary of SAR jamming and anti-jamming development is more instant under the modern warfare. Accordingly, the research of jamming simulation in a SAR distribute simulation system based on HLA has an important practical significance.This dissertation analyzes the method and characteristic of SAR jamming particularly, and gives the mathematic model of jamming wave. Then, it introduces HLA framework selectively, and described the method to manage the federates in HLA with the Object-Oriented thinking. At last it contained some description of HLA serves in this system.In the implement part of this dissertation, according to the software development process, it tells how to implement a federate of jammer framework using the Object-Oriented technology. To separate the simulation routine and the implement of any part makes the developer of one part mustn't know the inside of other parts, and it is propitious to the cooperation between developers.This dissertation implements multi-thread management under this framework. The framework provides a thread pool to manage multi-thread. so the developer only needs to separate their target data, in order to improve the efficiency of computation.Make some uni-test for the completed jammer federate. Finally test the whole system, and give the test result. Validate the design and implement of model and system.
