摘　　要：针对传统的着陆引导雷达天线角基准校验方法的电磁辐射量大、抗环境干扰能力弱、工作效率低等缺点,提出并实现了一种改进的校验仪。改变被测天线主动发射大信号方式为被动接收小信号,校验仪远端采用三轴程控转台加伺服控制机构实现对标准源天线的精确控制,配合近端的操作软件,在天线测试外场150~250 m遥控源天线动作,具有自动寻峰、数据判断存储功能。改进后对人体辐射量仅为原来的1/850000,测试人员数量从4人减少为2人,时间从2 h缩短到30 min以内。实验证明改进的雷达天线角基准校验仪完全可以替代传统的校验仪。For traditional calibrating method of the antenna angular reference of landing guidance radar,a large amount of electromagnetic radiations is unavoidable,the capacity of resisting disturbance is lower and the work is inefficient.An improved method is proposed.The measured antenna received small signal instead of transmitting large signal during the testing procedure.Three axis programmable turntable and servo controller were adopted at far field testing to control the horn antenna move precisely,and working with the near-end operational software.The horn antenna can be remotely controlled between the distance of the 150 to 250 meters.Peak-seeking automatically and data logging and storage were realized as well.Compared with the traditional calibrating method,the electrical radiation reduced to 1∶850000,the testing stuff reduced from 4 to 2 and the testing time reduced from 5 hours to 0.5 hour.The improved calibrator which is proved by the experiments can replace the old one completely.
