Hybrid monitoring collision avoidance warning method and system for multiplex omni-directional antennas

Abstract

The invention discloses a hybrid monitoring collision avoidance warning method for multiplex omni-directional antennas. An antenna system is shared by an S-mode responder and an ACAS through control over a base band and a radio frequency front end; in the processing process, a monitoring range of an aircraft is divided into an active monitoring area and a passive monitoring area, and fuzzified ACAS inquiry period is adopted, so that collisions between ACAS inquire and S-mode response are reduced, and the system response rate is improved on the premise that the maximum monitoring range is ensured; after ACAS measuring data and ADS-B information are integrated in the warning data processing process, the closest approach point between an invade aircraft and the aircraft is obtained finally, and corresponding TA / RA warnings are provided for an aviator to prevent aircraft collision. The hybrid monitoring collision avoidance warning method for the multiplex omni-directional antennas has the advantages that equipment size is reduced, and power consumption is reduced.

Description

technical field [0001] The invention relates to an anti-collision warning method for ensuring aircraft flight safety, and belongs to the field of aviation technology Background technique [0002] In recent years, with the development of the aviation industry, the density of aircraft per unit of airspace is increasing. The traditional air collision avoidance system is greatly reduced with the complexity of the flight state of the aircraft; both ACAS and ground air traffic control surveillance use 1030 / 1090MHz frequency, ACAS and ground air traffic control inquiries are answered through the airborne transponder, so it is necessary to reduce the ACAS interrogation rate through a hybrid surveillance collision avoidance system to reduce radio interference problems. [0003] The hybrid monitoring and anti-collision warning technology means that the ACAS airborne collision avoidance system uses ADS-B1090MHz extended message information to receive ADS-B information from adjacent ai...

Problems solved by technology

Under this operating mechanism, eight receiving channels are required to complete the reception of radio frequency signals, so the system is large in size, high in power consumption, and low in reliability, and is not suitable for mixed monitoring and anti-collision warning of military aircraft such as fighter jets and drones.
