Design And Implementation Of Data Processing And Display Control Components For Software-Defined Radar

The development of radar digital technology has laid a technical foundation for the birth of software-defined radar.The characteristics of software-defined radar hardware can be reconfigured,software can be reconstituted,and requirements can be defined,which is the only way for the future development of modern radar.Taking the software radar as the research background and the component as the research unit,this paper designs and implements the data processing and display control components,which expands the richness and completeness of the software-defined radar system.In this paper,the research status and development prospect at domestic and international software-defined radar are deeply investigated,the development achievements and trend of display control and components are explained,which shows the important significance of display control and components in software-defined radar.On the basis of research results,relying on the CPU software-defined radar system platform,based on the layered structure of the software-defined radar,it focuses on the functional technical requirements of each layer.Furthermore,on account of the software-defined radar algorithm component specification standard,the three-layer design structure of the algorithm component is given,and the interface functions of each layer are introduced in turn.On the basis of analysis and research of the principle of data processing algorithm,according to the structure of the algorithm component,the realization scheme of the data processing component combining the component and the composite component is designed.In addition,this paper also proposes the design pattern of MVCI display and control components,and explains the functions of different layers of display and control components and the interaction between them.Taking the generality and extension of display and control components as the design goal,the form container and data management interface that can support display and data interaction of display and control components are designed.This paper introduces the implementation of P display,map display,SAR display,and storage-playback components.Relying on the above components,the implementation and verification of the custom radar display and control application scheme is completed.Finally,the paper introduces the system parameters and data processing flow of the C-band phased array radar system.According to the processing flow,the CPU hardware platform is used to build the application scheme of the radar system,and the operation resource occupation and processing consumption of its components are occupied.The evaluation and analysis of the software radar system shows many advantages such as stability,reliability and practicability of the software-defined radar system.
