摘要
为便于学生全面理解S模式二次雷达数据链工作原理,针对实验资源不足、学生参与度低的问题,在深入分析S模式数据链信号格式基础上,开发了一套S模式二次雷达数据链仿真实验平台。该平台由地面询问机和机载应答机组成,实现了信号生成、数据收发、信号处理及场景设计功能,且以可视化形式对各阶段信号波形进行展现。实践表明,该实验平台能够满足S模式数据链实验教学需求,充分调动了学生学习积极性,教学质量得到显著提升。
In order to let students fully understand the principles of mode S secondary radar data link,aimed at the problem of insufficient experimental resources and low student participation,a simulation experiment platform for mode S secondary radar data link was developed based on an in-depth analysis of signal format of mode S data link.The platform was implemented with the functions of signal generation,data sending,data receiving,signal processing and scenario design,and was consisted of interrogators and transponders.In addition,signal waveform of each stage can be visualized in the platform.Practice shows that the experimental teaching needs of mode S data link were met by the platform,students’enthusiasm for learning was fully mobilized and teaching quality was significantly improved.
