A semiautomatic radar surveillance system using a time-compression display 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 1, 2, 3, and 4minute, three levels of clutter density 0.016, 0.032, and 0.064 piecessquare nautical mile, and two levels of practice replications were investigated. Results indicate that increases in target introduction rate generally degrade subject performance e.g., track initiation time increases, clutter has little effect on performance, track initiation is sensitive to practice, improving from the first replication to the second, and track maintenance is relatively insensitive to practice. The dynamic characteristics of surveillance tasks require the development of a queuing model to describe human performance in semiautomatic surveillance systems. Author
