设计了一种低成本的反射面天线实验方法,利用地球同步卫星做信号源,解决反射面天线实验中不易满足最小测试距离的问题,设计了适合实验的二维转台和接收装置,用简单的测试仪器和设备替代了价格昂贵的微波收发设备。通过对实验方法的探索和实践,获得了良好的实验结果,测试精度符合反射面天线教学实验的要求。该项新实验在近三年的本科教学中使用,并不断完善实验步骤和方法,对提高微波技术与天线课程教学效果,培养学生天线工程方面的实践能力和动手能力,作用十分明显。
A low-cost experimental method of reflector antenna is designed. With the use of the geostationary satellite as the signal source and the difficulty of meeting the minimum test distance in the reflector antenna experiment, a two-dimensional turntable and receiver suitable for experiment are designed. Test equipment and equipment to replace the expensive microwave transceiver equipment. Through the exploration and practice of the experimental method, good experimental results have been obtained, and the test accuracy accords with the requirements of the experimental teaching of reflector antennas. The new experiment in the past three years of undergraduate teaching, and continue to improve the experimental steps and methods, to improve the microwave technology and antenna course teaching effectiveness, training student antenna engineering practical ability and practical ability, the role is very obvious.
