Research On Data Management System Of Hypersonic Vehicle Electromagnetic Scattering Characteristics Based On Multi Platform

With the development of computational electromagnetics,the demand for military applications and the continuous improvement of computing power,the computation of electromagnetic scattering characteristics of hypersonic vehicle targets as a frontier research topic has been paid more and more attention by researchers.Hypersonic vehicle is usually calculated by its own software because of its characteristics.The data generated by the electromagnetic scattering characteristics of hypersonic aircraft are characterized by large amount of data and diverse data formats.It is very difficult to manage by traditional methods,and it is also not conducive to the development of R & D personnel in later stage.Therefore,it is necessary to manage by the way of system software.The complex computation is carried out on the server.Considering the diversity of the server software operating system,the software system needs the characteristics of cross platform compatible Linux and Windows system.After studying the GUI(Graphical User Interface)development program and database software,we decided to develop a data management system based on C/S system architecture and Qt and My SQL.After studying the data characteristics of the electromagnetic scattering characteristics of the hypersonic vehicle and the needs of various personnel to the system platform,the architecture and function structure of the data management system under the two conditions of LAN scope and single machine operation are designed.Taking the Windows system platform as an example,the integrated development environment Qt Creator of Qt is used to realize the functions of project creation,database connection,database management,data import,data query and display,data modification and export,and the implementation logic is discussed.The key technologies such as My SQL database driven compilation,data storage relation table,database operation method,data normalization flow processing,data high-speed import,data drafting principle are expounded.Hypersonic aircraft electromagnetic scattering data management system has many other applications,such as radar detection distance estimation,data file processing,conversion and integration with other platforms.Taking the application of the sky wave over the horizon radar as an example,the sky wave over the horizon radar is introduced,then the principle of estimating radar detection distance by using RCS is explained,last how to realize this function on the original operation system is expounded.The combination of data management system and system platform such as electromagnetic scattering calculation and target trajectory analysis is discussed.The graphical user interface of the hypersonic vehicle electromagnetic scattering characteristic data management system is displayed under the version of Linux operating system represented by Redhat.The user interface is displayed for the extended application of the original data management system under the Windows operating system.Taking a certain type of aircraft as an example,the numerical results of the data management system extended to the target detection ability of the sky wave over the horizon radar are displayed and analyzed,and the data results of the data management system in the data processing are extended and applied.Finally,the whole paper is summarized,and the optimization of the processing speed,security and stability of the system platform is prospected.
