Aircraft Track Initiation And Maintenance In A Single Operator Simulated Surveillance System Technical Report I

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 the surveillance area (75 by 75 nautical miles), initiate automatic tracking of these targets, and reinitiate (maintain) 'lost' tracks when automatic tracking failed. Four target introduction rates (2, 3, and 4/minute and a distributed rate with a mean of 2.5 targets/minute), three levels of clutter density (0.016, 0.032, and 0.064 pieces per square nautical mile), and two levels of target velocity (500 and 900 knots) were investigated.
