针对大型相控阵不易采用传统转台法进行远场测试的问题，提出了一种基于人工运动源的现场测试方法实现对方向图的测试。该方法利用航空平台搭载测试系统和高精度定位测姿系统，同步记录时间、接收信号强度和三维位置信息，通过后续数据处理得到方向图。并针对测试过程中存在的误差进行了分析和修正，最后通过计算机仿真验证了方法的有效性。

Traditional far-field test method can hardly be used to carry on far field test of a large phase array be-cause of the difficulty in building a large turntable . To solve the problem,a site method based on artificial source is proposed to test the radiation pattern . The method uses an airborne platform embarking test system and high-precision positioning and orientation system to synchronously record the time,amplitude of the receiving signal and three-dimensional position . Through data processing of the recorded data the radiation pattern can be ob-tained . The test errors are also analyzed and corrected . Finally,computer simulations are provided to illustrate the validity of the proposed method .
