Research And Implementation Of Softwareized Radar Display And Control Platform

With the maturity of digital technology and the diversity of military demand,software-defined radar with the characteristics of hardware reconfigurable,software reconfigurable,and requirements definable has become an important topic of radar system research.Display and control platform is the upper application of software radar,which carrys important functions of human-computer interaction.This article proposes a one-to-one mapping method based on binary search to realize real-time coordinate transformation of P display,and a software-based radar display and control platform with software reconfigurability and function expansion is designed and implemented based on development unit of components.Firstly,this thesis investigates the research background and research status of software radar at home and abroad,and introduces the development process of the display and control platform and the realization method of the traditional display and control platform,then expounds the necessity of research on software radar display and control platform.Taking a software radar system as an example,this article introduces in detail the open architecture of software radar,the technical characteristics of modularization,digitization and standardization,and the development concept of "oriented to actual needs,with software technology as the core".By comparing the characteristics of different development languages and technical frameworks,as well as fully considering the development cost,software portability and other issues,Qt was identified as the development tool for the platform.Secondly,in order to solve the problem of display delay and missing points in P display direct coordinate transformation under large data volume,this thesis introduces and compares the overall mapping method,the one-to-one mapping method and the improved method of the one-to-one mapping method in detail,and proposes a one-to-one mapping method based on binary search to realize real-time coordinate transformation of P display.On the premise that the accuracy of the one-to-one mapping method remains the same,use local optimization instead of global optimization to establish mapping table,which improves remarkably the efficiency of the algorithm.In addition,the chain storage structure of the mapping table and the corresponding search algorithm are designed to solve the problem of data redundancy and resource waste.Lastly,this paper evaluates the computational efficiency and accuracy of the one-to-one mapping method based on binary search,and verifies the feasibility and effectiveness of the method.Thirdly,for the purpose of software reconstruction and function expansion,the design requirements of the display control platform have been deeply analyzed.At the same time,the application modules including the display control terminal,component library management and log service are determined,and introduces the specific functions of the application sub-modules.In the component-based development mode,the display and control components are designed and implemented,meanwhile the application scheme of the display control terminal is quickly built,then the component management library and the log service application module are implemented.Finally,this paper has carried out a software transformation of a radar simulation system,and applied the functional modules of the software radar display and control platform to the radar simulation system to complete the functional verification and performance analysis of the platform.The results show that the system has good real-time and stability.
