Book Description
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.

Book Description
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.

Book Description
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 4/minute), three levels of clutter density (0.016, 0.032, and 0.064 pieces/square 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).

Book Description
Decision Information is a collection of manuscripts presented at the 1976 Workshop on Decision Information for Tactical Command and Control, held at the Airlie House in Airlie, Virginia. This workshop provides the scientific managers of the Service Office of Research with the knowledge allowing them to formulate research programs relevant to military problems in decision information. This book is organized into three parts encompassing 28 chapters. The first part consists of presentations in systems approach to large-scale human and man-machine systems, benefit-cost models for decision makers, team decision models, and cubic interpolation processes. The contributors highlight the various theoretical aspects of the models and illustrate their scientific usefulness to many problems in the society. The second part explores the statistical models in the areas of scheduling systems, combat models, logistic structures, inventory systems, Bayesian and empirical Bayesian reliability models, parameter estimation schemes, and memory models. This part also presents a broad spectrum of mathematical sciences that illustrate the two main facts that make most problems, namely, the number of variates in the model and the degree of uncertainty. The third part is devoted to military presentations, emphasizing the problem in command, control, and communication. This part also considers the implementation of fuzzy sets in military command analysis, decision support in a conflict environment, and data-poor modeling.
