    • A field unit for warning of a danger of collision between an aircraft and an obstacle, in particular a topographical ground obstacle or an obstacle formed by a mast, building or aerial cable structure, comprises a multi-part tubular mast having devices for fixing a solar panel and a radar antenna; an elongate radar antenna in an environment-protective casing, which, with an electronics unit, forms a radar system for synthesized radar detection of an aircraft in a radar coverage area; a central processing unit for identifying on the basis of information from the radar system an aircraft which is in a zone of the radar coverage area and which on the basis of radar information such as direction, distance and/or speed computes a collision danger area; and a high-intensity light system and radio transmitter system that can be activated by the central processing unit upon detection of an aircraft in a collision danger area. The radio transmitter system may be a VHF or UHF radio transmitter system for providing a radio signal modulated by an audible warning signal, preferably a voice warning signal, whilst the light system preferably comprises a stroboscope light system. The field unit is arranged for communication with other similar field units for remote activation of light or audio warnings in a neighbouring field unit.
    • 用于警告飞机和障碍物之间的碰撞危险的现场单元,特别是地形地面障碍物或由桅杆,建筑物或航空缆索结构形成的障碍物,包括多部分管状桅杆,其具有用于固定太阳能 面板和雷达天线; 在环境保护壳体中的细长雷达天线,其中电子单元形成用于在雷达覆盖区域中的飞行器的合成雷达检测的雷达系统; 基于来自雷达系统的来自雷达覆盖区域的飞机的信息,其基于诸如方向,距离和/或速度的雷达信息来计算碰撞危险区域的中央处理单元; 以及在碰撞危险区域中检测到飞行器时可被中央处理单元激活的高强度光系统和无线电发射机系统。 无线电发射机系统可以是VHF或UHF无线电发射机系统,用于提供由可听见的警告信号调制的无线电信号,优选地是语音警告信号,而光系统优选地包括频闪镜系统。 该场单元布置成与其他类似的现场单元进行通信,用于远程激活相邻现场单元中的光或音频警告。
