LOOKOUT ASSIST DEVICE FEASIBILITY STUDIES. VOLUME 1. HUMAN FACTORS COLLISION STATISTICS, ECONOMICS FACTORS OPERATIONS RESEARCH, SENSOR TECHNIQUES

A study of human factors and collision statistics showed that a proximity warning device would fit into the traditional mode of ship operation and should materially improve the chance of avoiding collision. Economics studies and questionnaires indicated acceptable price and maintenance levels. An operational analysis defined range and bearing accuracy requirements. A sensor study showed that an adaptation of radar techniques, possibly backed up by passive sonic sensors, will offer the most reliable and inexpensive approach for solving the proximity sensing requirement. A study of displays indicated acceptable techniques for transferring sensor outputs to the lookout. Although the studies were directed primarily towards the feasibility and desirability of a proximity warning device, certain other problem areas were probed, notably the degree of danger assessment and the need for better maneuver plan data. The conclusion was that the 'Tau" criterion should be used in the danger assessment function rather than the orthodox constant bearing criterion. Additionally, the conclusion was reached that the effectiveness of maneuver planning can be enhanced by true motion displays, but that a high resolution, high information rate radar capable of displaying target aspect is probably more useful.
