摘要
针对电磁场、微波与卫星通信等射频类实验课程多以仿真演示为主、缺乏配套实验设备以及缺少系统性贯通实验等问题,开发了电磁场与微波卫星通信实验平台。该实验平台由实验操作模块和二次开发模块组成。基于电磁场与电磁波子模块、微波通信系统子模块、卫星通信系统子模块以及嵌入式测量仪器子模块,实验操作模块真实地还原了电磁波传输、微波收发链路、卫星中继链路转发等过程,进而实现了多门射频类实验课程线上线下、虚实结合的贯通性教学模式应用。二次开发模块与先进设计系统(ADS)、高频结构仿真(HFSS)软件相融合,并结合仿真例程进行实验模块设计,从而丰富了射频类课程的实验教学应用。该平台旨在帮助学生理解并掌握抽象理论公式,实现对射频类课程的知识整合。
In the electromagnetic field,microwave satellite communication and other radio frequency courses,experiments mainly focus on simulation demonstration and lack of supporting experimental equipment and systematic through experiments.Therefore,an experimental platform for electromagnetic field and microwave satellite communication was developed.The experimental platform consists of experimental operation module and secondary development module.Based on the electromagnetic field and electromagnetic wave sub-module,microwave communication system sub-module,satellite communication system sub-module and embedded measuring instrument sub-module,the experimental operation module truly restores the process of electromagnetic wave transmission,microwave transceiver link,satellite relay link transmission and other processes,and then realizes the application of online and offline,virtual-real through teaching mode of multiple radio frequency experimental courses.The secondary development module is integrated with Advanced Design System(ADS),High Frequency Structure Simulation(HFSS),and the experimental module is designed by combining simulation routines,so as to enrich the experimental teaching application of radio frequency courses.The platform aims to help students understand and master the abstract theoretical formula and realize the knowledge integration and comprehensive application of radio frequency courses.
