摘　　要：该文首先提出了"软件化雷达"(Software Radar)这一新技术概念,并对"软件化雷达"的定义、定位、技术特点以及可能带来的影响进行了系统阐述。文中指出,"数字化雷达"、"软件化雷达"和"智能化雷达"是现代雷达系统技术发展的3个不同阶段,目前正处于从"数字化雷达"向"软件化雷达"过渡的重要时期。"软件化雷达"的核心特征体现在:标准化、模块化和数字化特征,开放式的体系架构以及"以软件技术为核心,面向应用需求"的开发模式。和传统的"以硬件技术为核心,面向专用功能"的开发模式不同,"软件化雷达"注重软件和硬件的解耦,从而使得可以通过软件定义方式快速开发雷达系统,并灵活地实现系统资源配置、功能扩展和性能提升,以满足实际应用的需求。然后,为了进一步阐述"软件化雷达"系统的技术特点,该文对清华大学研制的"软件化雷达"信号处理系统RadarLab2.0进行了介绍。最后,结合对空情报雷达的应用需求,对"软件化雷达"技术的发展给出了建议。In this paper, the definition and the key features of Software Radar, which is a new concept, are proposed and discussed. We consider the development of modern radar system technology to be divided into three stages： Digital Radar, Software Radar and Intelligent Radar, and the second stage is just commencing now. A Software Radar system should be a combination of various modern digital modular components conformed to certain software and hardware standards. Moreover, a Software Radar system with an open system architecture supporting to decouple application software and low level hardware would be easy to adopt ＂user requirements-oriented＂ developing methodology instead of traditional ＂specific function-oriented＂ developing methodology. Compared with traditional Digital Radar, Software Radar system can be easily reconfigured and scaled up or down to adapt to the changes of requirements and technologies. A demonstration Software Radar signal processing system, RadarLab 2.0, which has been developed by Tsinghua University, is introduced in this paper and the suggestions for the future development of Software Radar in China are also given in the conclusion.
