An Evaluation ot the U.S. Coast Guard's Physical Detection Model for Visual Search

Abstract

In 1983, an analytical method for modeling visual search/detection performance was developed for the U.S. Coast Guard. This method, known as the physical detection model, was implemented in a computer software package called VSW. VSW is resident on the Coast Guard's PRIME computer facility at Governor's Island, N.Y. This study analyzes the foundations of the physical detection model, its mathematical modeling approach, and its computational methods. Software corrections and modifications made in conjunction with this study are documented and discussed. A comparison of sweep widths and lateral range curves predicted by the model to those actually achieved during two recent visual detection experiments is provided. Recommendations for improving model accuracy and applicability are made. Keywords: Search and Rescue, Visual Detection, Sweep width, Visual search, Detection modeling, Visual perception, Visual targets.
