Aircraft track initiation and maintenance in a single operator simulated surveillance system

A semiautomatic radar surveillance system using a time-compression mode for display of real-time radar data was simulated. Subjects were required to detect targets entering a surveillance area of 300 by 300 nautical miles, initiate automatic tracking of these targets, and reinitiate: maintain lost tracks when automatic tracking failed. Three target introduction rates, two levels of clutter density, and three levels of target velocity were investigated. .DLN : KILLED, PER TD 78-110
