Abstract

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.

  1. 1. 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, characterised in that it comprises: a multi-part tubular mast having a fixing device on one side face for a solar panel and a fixing device at an upper end for a radar antenna; an elongate radar antenna arranged vertically in the longitudinal direction and having a plurality of antenna panels and provided with an environment-protective casing, which radar antenna is in communication with radar electronics to form a radar system for synthesized radar detection of an aircraft in a radar coverage area; a central processing unit in communication with the synthesized radar detection radar system for processing information from the radar system, which information includes at least one indication of direction and several indications of distance or at least one indication of direction, one indication of distance and one indication of speed, and for identifying a radar system detected aircraft that is in a zone of the radar coverage area computed by the central processing unit as a collision danger area on the basis of the information; a high-intensity light system connected to and controlled by the central processing unit for providing a high-intensity light warning signal, the light system being activatable by the central processing unit upon the detection of an aircraft in the collision danger zone; a VHF or UHF radio transmitter system connected to and controlled by the central processing unit for providing a radio signal modulated by an audible warning signal, the VHF or UHF radio transmitter system being activatable by the central processing unit upon the detection of an aircraft in the collision danger zone; and an electric power supply system comprising a solar panel secured to a fixing device, a chargeable back-up battery and a power supply control for power supply to the radar system, the central processing unit, the high-intensity light system and the VHF or UHF radio transmitter system.
