| With the continuous development and maturity of digital technology,Software Radar came into being.Software Radar is a new type of radar system,which is based on standardized and modular digital platform and has open architecture.It adopts application-oriented development mode and system functions are defined,expanded and reconstructed by software.It is a significant orientation for the development of future radar systems.Focusing on the issues of poor compatibility and versatility in traditional radar systems,as well as the strong coupling between software and hardware,research on the techniques of online reconfigurability for Software Radar is conducted in this thesis,which lay emphasis on the online reconfigurable open architecture,service-oriented component model and online configurable core framework.The main contents of this thesis are as follows:1.As for poor compatibility and versatility,an online configurable open architecture based on service for Software Radar is designed.Open architecture adopts the layered,modular design philosophy,which helps lower the coupling in different levels of radar systems and realize the flexible expansion of radar system framework.2.As for the strong coupling between radar system function modules and difficulty in independent development,a service-oriented component model is designed.Component model are designed using service-oriented programming technology.The communication between components is based on registration lookup mechanism for services and publish subscription mechanism for events,which reduces the coupling between components and realize the independent development of the function modules in radar systems.3.As for the strong coupling between software and hardware and the difficulty in software reconfiguration,a configurable management system for software radar is designed.This design of configurable management system is base on OSGi(Open Service Gateway Initiative)technical specification,which supports dynamic installing,uninstalling and updating and realize the online update and dynamic reconfiguration of radar systems.In the end,the experimental test scheme is designed and the testing platform is established to conduct function verification,cross-system verification and cross-platform verification for online reconfiguration techniques on Windows and Ubuntu system based on X86 framework and Manifold2 system based on ARM framework respectively.The result shows that the upper-layer software application of radar system can install,uninstall and update dynamically according to demands in different platforms and systems,which realize the online reconfiguration function for Software Radar. |
