Development of Improved TCAS II Surveillance and Interference Limiting Functions

摘要

This paper describes the development and validation of improved TCAS II intruder surveillance tracking and interference limiting algorithms. Im- provements in interference limiting were prompted by the FAA Spectrum Management Office and by international aviation administrations in order to further reduce interference to ground-based air traffic control surveil- lance by TCAS 11. Improvements in surveillance tracking were prompted by air carrier pilot organizations in order to increase the level of traffic situational awareness offered by the TCAS II display. The new algorithms are included in a proposed new version of TCAS II MOPS DO-185A which is commonly referred to as Change 7.0. TCAS II change 7.0 units will be introduced into the US airspace beginning as early as 1999 as part of a program to implement improvements in both TCAS II surveillance and collision avoidance.
