| 摘要： | The traffic Alert and collision Avoidance System (TCAS) is a beacon- based airborne collision avoidance system that operates by providing air-to-air surveillance of all transponder-equipped aircraft. Enhanced TCAS II uses more accurate intruder bearing data to allow it to generate horizontal resolution advisories. TCAS equipment operates by interrogating once each second and measuring reply delay to determine the range of nearby aircraft. The replies to these interrogations contain the altitude of the aircraft if it includes an encoding altimeter. TCAS II uses the range and range rate of the aircraft to determine if it is a collision threat. The relative altitude and altitude rate of the aircraft is used to determine proper maneuver direction for collision avoidance. This report documents tracking techniques developed by Lincoln Laboratory for use by TCAS II equipment in tracking aircraft equipped with ATCRBS transponders. It describes two correlation and tracking algorithms used for ATCRBS replies. On algorithm is for aircraft that report altitude and the other is for those that do not report altitude. |
