本文针对传统雷达存在的主要问题,着眼软件化雷达发展与应用需求,对软件化雷达的开放性、灵活性及敏捷性等主要特性进行了系统分析,给出了开放性、灵活性和敏捷性的概念内涵及实现要求,并将软件化雷达与传统雷达进行了全面的对比分析,揭示了软件化雷达的本质特征和性能优势。在此基础上,提出开展软件化雷达技术体制分析的总体思路,从软件化雷达系统架构、软件化雷达前端、软件化雷达处理平台及软件环境、软件化雷达应用软件等方面系统分析了软件化雷达技术实现要求,指出基于层次化模型的模块化开放式系统架构是软件化雷达设计的顶层要求,是实现软件化雷达系统开放性、灵活性、敏捷性的重要基础和灵魂。必须打破传统雷达前端设计思路束缚,充分开放前端资源,合理划分功能模块,实现模块间解耦和组件化应用。必须在传统雷达后端基础上,采用集成框架和中间件等技术,实现软硬件平台解耦和架构可扩展。应用软件必须采用组件化设计,并注重提高组件的复用性。根据分析结果,明确提出开放式系统架构、层次化系统设计、模块化功能划分、组件化软件开发以及软硬件解耦等是软件化雷达技术体制的本质特征和核心内容,其根本要求是遵循软件化雷达相关标准规范,从而为软件化雷达技术应用及装备发展提供指导。

The detection performance of the traditional radar system,which is widely used at present,has reached a very high level.However,due to the outstanding problems such as closed system architecture,binding of function to hardware,and tight coupling of hardware and software,it has caused a series of problems such as complex equipment spectrum,single function solidification,maintenance support,and upgrading and improvement difficulties,and long development cycle,large resource consumption,and slow application of new technologies,it is difficult to adapt to rapidly changing military needs and rapid technological development.New technological systems must be developed to solve these problems.Aiming at the main problems existing in traditional radar,this paper focuses on the development and application requirements of software defined radar,and systematically analyzes the main characteristics of the software defined radar such as openness,flexibility and agility.The concept and realization requirements of openness,flexibility and agility are given,and the essential characteristics and performance advantages of the software defined radar are re vealed by comparing the software defined radar with the traditional radar.On this basis,the general idea of developing software defined radar technical system analysis is put forward,the realization requirements of software defined radar technology are systematically analyzed from the aspects of software defined radar system architecture,front-end,processing platform,software environment and application software development.It is pointed out that the modular open system architecture based on hierarchical model is the top requirement of software defined radar design,and is the important foundation and soul of realizing the openness,flexibility and agility of software defined radar system.It is necessary to break the shackles of traditional radar front-end design ideas,fully open front-end resources,rationally divide functional modules,and realize the decoupling and componentization of modules.On the basis of traditional radar back-end,we must adopt integration framework and middleware technology to realize software and hardware platform decoupling and architecture scalability.The application software must be designed in a componentized manner and focus on improving component reusability.According to the analysis results,it is clearly proposed that open system architecture,hierarchical system design,modular function division,component software design and software and hardware decoupling are the essential characteristics and core contents of the software defined radar technology system,the basic requirement is to follow the relevant standard specifications of software defined radar,so as to provide guidance for the application of software defined radar technology and the development of equipment.The software defined radar technology system is different from the traditional radar technology system.This technology system is a new technology system produced by changing the traditional radar design method and research and development mode,starting from improving the openness,flexibility and agility of the radar system.Its core content is open system architecture,hierarchical system design,modular function division,componentized software development,software and hardware decoupling and other technologies.These technologies determine the openness,flexibility and agility of the software defined radar that the traditional radar does not have,and give the software defined radar new capabilities based on the performance of the traditional radar.And this capability has become more and more important,and its importance even exceeds the traditional radar performance to some extent,becoming the goal of the development of a new generation of radar.Therefore,it is of great significance to develop software defined radar technology system.
