| 借鉴飞机天线方向图地面自由空间测试场测试方法，利用直升机
空中悬停特性进行天线方向图测试，以达到节省试飞架次的目的。分析了如何进行直升机悬
停位置的选择以及直升机到测试点的距离和垂直高度的计算，总结了直升机超短波天线方向
图测试中的定点悬停试飞驾驶技术。该试验方法在飞行试验中得到了验证，与传统试飞方法
进行对比，工作效率提高2倍。 |

| Abstract: |
| By learning from the aircraft antenna pattern ground free-space test method,heli
copter′s hovering character is applied to measure antenna radiation pattern
, in order to save the flight test sorties.The methods for the selection of the
hovering point and the calculation of the distance and the height from the instr
ument site to the helicopter are analysed. The fixed-point hovering flight drivi
ng techniques are summarized in helicopter-borne VHF antenna radiation pattern m
easurement. The test method is verified in the flight test, and compared with th
e traditional one,the work efficiency is tripled. |
| Key words: helicopter VHF antenna radiation pattern measurement fixed-point hovering |
