Method of altitude track initialization in an aircraft tracking system
free download
A method of processing a plurality of replies of target aircraft provided in response to interrogation signals from the surveillance aircraft during surveillance periods to determine whether an altitude track be initialized for use in a traffic alert and collision avoidance

Method of multipath track reduction in an aircraft tracking system
free download
Abstract In a Traffic Alert and Collision Avoidance System (TCAS), response to interrogations can result in normal, multipath (image), and mixed multipath (potential image) tracks. The method for reducing the number of false tracks includes the steps of selecting a

Method of track merging in an aircraft tracking system
free download
A method of processing a plurality of tracks representative of one or more target aircraft in a vicinity of a surveillance aircraft, where each track is generated in response to target reply signals provided by the target aircraft in response to interrogation signals transmitted by the

Method of improved initial transmission of acquisition and tracking interrogations in an aircraft tracking system
free download
In an aircraft having an aircraft tracking system (ATS), the aircraft being a monitoring aircraft, the monitoring aircraft interrogates target aircraft in the vicinity of the monitoring aircraft in order to determine potentially dangerous situations. The target aircraft responds to the

Method of reducing false tracks due to suppression pulse replies in an aircraft tracking system
free download
In an aircraft which has a tracking system, the aircraft interrogates all target aircraft in the vicinity of the aircraft in order to determine potentially dangerous situations. The interrogation has a predetermined interrogation sequence which includes interrogation

Method of determining radio frequency link reliability in an aircraft tracking system
