摘要
以无人直升机平台的空地数据链机载天线布局设计要求为研究背景,通过使用FEKO通用软件对机身不同区域天线方向图进行仿真,明确天线受飞机平台结构和外挂设备遮挡影响而形成的通信"盲区",通过对机载天线装机位置合理的布局实现空地数据链方位360°、俯仰30°通信,解决空地数据链通信的"盲区"问题。
Air-ground data link system is an important part of unmanned helicopter system. It is the link between the air and the ground. The real-time transmission of air-ground data link is related to the performance of unmanned helicopter and the security of platform. The performance of airborne antenna will directly affect the working state of data link system. The design requirements of airborne antenna layout for unmanned helicopter are studied. By using the universal software FEKO, the antenna pattern of different region of the fuselage is simulated. The blind zone formed by the influence of the platform structure and the shielding of external equipment are clearly defined. Through reasonable layout of loading position of airborne antennas, it will achieve air-ground data link to communication with azimuth 360° and elevation 30° of airborne antennas. It will solve the blind zone problem of air-ground data link.
