软件化雷达技术是通过构建开放式的体系结构，在研制雷达操作环境的基础上，实现雷达系统功能通过软件定义、扩展和重构的新一代雷达技术。文中从软件化雷达的需求、国内外研究现状、内涵及技术架构、关键技术及发展设想等方面进行了分析和论述。通过软件化雷达技术的研究，最终可形成快速响应新军事需求、缩短研制周期、提高维护保障和升级换代的能力。

Software defined radar technology is an open system architecture technology. Based on radar operation environment, the functions of radar system can be easily defined, extended, and reconfigured to adapt to the requirements. This paper analyses the requirements, domestic and international research status, the concept and system architecture, primary technologies and development ideas of software defined radar. With research on software defined radar technology, abilities for quickly reacting to new military requirements, shortening research period, improving maintenance and upgrading and updating can be realized.
