摘要
为解决在雷达信号处理机研制过程中缺乏作战场景和回波输入的问题，提出了高置信度的雷达目标回波信号和战场复杂电磁环境设计方法。通过分析弹道导弹目标发射、飞行工作流程，设计了相应的雷达模拟器系统构架，确立了雷达面临的作战场景和回波信号、噪声、杂波、干扰的模型。基于复杂场景规划，利用图形处理器（GPU）处理平台实时产生雷达信号，生成高置信度的复杂电磁环境回波输出。该雷达目标模拟器的研制可以解决雷达研制过程中接口、功能和性能验证问题，为雷达提供更加真实和完备的测试场景，加快雷达系统研制进度，提升雷达的综合性能测试能力，具有很强的工程应用价值。
In order to solve problems about the lack of combat scenes and echo simulation during the development of radar signal processor, it is proposed to use radar target simulation technology to simulate high confidence radar echo and complex electromag- netic environment. Based on analyzing the launching and flying flow of ballistic missile target, the system framework of radar target simulator is designed, and the combat scenes and radar echo, noise, clutter and jamming model are established. Then based on complex scene planning, real time radar echo is produced using graphics processing unit and the complex electromagnetic environ- ment is generated. The radar target simulator can be used to solve the problem of testing radar interface, function and performance, provide more realistic and perfect test scenes, promote the radar system development and enhance the comprehensive testing capa- bility of radar system. The simulator has shown a strong valuable engineering application.
