摘　　要：针对超短波频段全向天线装机后的辐射方向图测试需求,提出了一种模拟多飞行状态的外场天线测试技术。外场测试系统采用地面固定辅助端测试小俯仰空域,空中无人机辅助测试大俯仰空域,着重阐述了无人机测试测试原理以及无人机绕飞或悬停方式下天线方向图测试方法。依据所提方法测试了不同俯仰角度下天线装机性能,从而验证不同机动条件下通信链路性能需求,为后续射频链路、射频兼容、射频隐身等测试验证提供基础数据和测试依据。In order to meet the requirements of antenna radiation pattern test of ultrashort wave omnidirectional antenna installed in the airplane,an out-field antenna measurement method of simulating multi flight state is proposed.Out-field measurement sys‐tem uses the ground fixed equipment to test the small airplane pitch attitude and the unmanned aerial vehicle to test the large air‐plane pitch attitude.The test principle of unmanned aerial vehicle and the antenna radiation pattern test method under the un‐manned aerial vehicle flying around or hovering are proposed.According to the method,the installation performance of antennas at different pitch angles was tested to verify the airplane performance requirements of communication links under different maneu‐ver conditions,providing basis data and test basis for subsequence radio frequency link,radio frequency compatibility and radio frequency stealth analysis.
