INVESTIGATION OF THE PERFORMANCE CHARACTERISTICS OF A DOPPLER KADAR TECHNIQUE FOR AIRCRAFT COLLISION HAZARD WARNING

摘要

This report presents the results of a computer simulation study of a cooperative doppler radar system for aircraft collision-hazard warning under development by NASA-Langley Research Center personnel. The system performance under multiple aircraft conditions, with particular emphasis on the problems of saturation and interference, is evaluated by simulation of the system using a data base consisting of twelve one-hour samples of aircraft position data obtained from the ground radar at the Atlanta, Georgia airport. In addition, the system error sources are determined by comparison of simulated data with flight test data, and other miscellaneous system problems are considered. Statistical studies of the data base have been previously documented in the Phase I final report [1] and Phase II interim report [2] of this contract.
