TCAS (Traffic Alert and Collision Avoidance System) Experimental Unit (TEU) Hardware Description

摘要

This document describes the hardware design of the TCAS Experimental Units (TEU'S) built by Lincoln Laboratory for the Federal Aviation Administration. These are experimental versions of TCAS (Traffic Alert and Collision Avoidance System), a system designed to alert pilots to nearby transponder-equipped aircraft and to assist them in avoiding collisions. The purpose in constructing the TEU's was to demonstrate a complete TCAS system that integrated the solutions to the many technical problems in areas ranging from elimination of multipath interference on the air-air link, to the modeling of aircraft trajectories and selection of appropriate commands, to the design of an appropriate interface between TCAS and the pilot. During the development process new problems were discovered and solutions developed, leading to the evolution of a large body of experience which is reflected in the standards that have been developed for commercial TCAS equipment.
