Simple Guide to Conducting Ground Search and Rescue Detection Experiments: Volume I [open pdf - 755KB]
"Effective sweep width is the missing critical element to determining meaningful and accurate Probability of Detection (POD) values. Probability of Detection is essential for search planning and evaluating the effectiveness of a search task. This tool is then used to determine where to send future resources out into the field to maximize the Probability of Success. Simply put, knowing effective sweep widths saves lives. The only way to determine effective sweep widths is to take searchers and perform field experiments in the environments actual searches take place. This guide will help searchers plan and conduct effective sweep width experiments."
