Design Of Ionospheric Radio Sounding Data Application System

At present, with the increasingly development of space communications systems and the human desire for outer space environmental awareness, people increasingly want to explore the outer space environment, While ionosphere is our only way to explore the outer space. Therefore, it is necessarey to do a study of the ionosphere, while the high-frequency diagram ionosphere radiosonde data measured in the analysis, processing, calibration and application is one important means of ionospheric research.For this research office of the independent research and development of the ionospheric radio detector hardware platform, this paper designed and implemented a set of ionospheric radiosonde data application system, detection of ionospheric data preprocessing analysis, computation and transmission after the computer monitor real-time map display and high-frequency binary file format is permanently stored in the computer, while the ionogram saved files developed with browsing, display, calibration, format conversion, information extraction, and other application software system functions by using Microsoft Visual Studio 2005 as an integrated development environment with C ++ language to complete the entire software system of each functional modules in the programming and debugging.The article first introduces the development and detection principle of ionospheric radio detection technology, and then introduces the ionospheric wave propagation in the ionosphere research lab radiosonde hardware and software systems. Ionospheric data processing system for radio frequency detector acquisition and display functions demand a high figure, the overall framework of the system design, implementation method gives the corresponding function modules, and create interactive interface, real-time rendering of high-frequency diagram. Using three layer architecture model for the overall design of software sysytem,improved the software system stability and extensibility.Achieve SBF file format conversion transformation and PIF file format in data conversion module. In the data used to draw and display module GDI + drawing and use double buffering technology and other ways to eliminate screen flicker,friendly and beautiful interface, and improve the stability of the system.Through debugging the overall system,the main interface clear and simple, user-friendly to operate.The system can complete the conversion Two data file format between PIF and SBF, display Ionogram and Manual calibration.Finally conclude the work for this thesis and software systems the problems and give advice and vision for the future work.
