Intercommunicating radar field units for system for avoidance of collision between an aircraft and an obstacle

摘要

A system for use in detecting and warning an aircraft of an obstacle is provided. The system comprises a network of field units each comprising a central processing unit in communication with a radar detection 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. The field units further comprise a communication device, connected to the central processing unit, arranged for communicating with other field units whereby the field unit can exchange information with other field units relating to a target detected within the field unit's range.
