摘　　要：为克服地面反射对测试的影响,一般会将标校塔建得较高,导致场地建设成本和难度大大增加。文中提出了一种基于多旋翼无人机平台的天线远测试系统设计方法。该方法利用多旋翼无人机可空中定点悬停的优点,搭载相应频段的测试标校载荷,在地面控制系统的控制下进行雷达天线远场测试,可大大增加天线远场测试的灵活性,使大型天线远场测试摆脱对测试塔的依赖,降低测试成本,具有较强的推广价值。The traditional far-field measurement of large antenna mostly relies on the field calibration tower.In order to overcome the influence of ground reflection on the test,the calibration tower will be built higher,usually up to hundreds of meters,which will greatly increase the cost and difficulty of site construction.A design method of antenna remote test system based on multi-rotor UAV platform is presented in this paper.This method takes advantage of multi-rotor UAV hovering in the air at fixed point,carries the test and calibration load of corresponding frequency band,and carries out the far-field test of radar antenna under the control of ground control system.It makes the far-field test of large antenna get rid of the dependence on the test tower and reduce test cost.It has a strong popularization value.
