Alternatives to Pyrotechnic Distress Signals; Supplemental Report

Abstract

This report is a follow-on to the Coast Guard Research and Development Center Report "Alternatives to Pyrotechnic Distress Signals; Laboratory and Field Studies," which capped a multi-year project effort that developed a specification for a light-emitting diode (LED) signal characteristic as an alternative to pyrotechnic, maritime distress signal flares as visual distress signals. This report describes the steps to determine the characteristic for a near-infrared (IR) component of the two-color visual distress signal so as to provide a night-vision imaging system user a signal, conspicuous against certain lighting conditions, at six nautical miles, in 10 miles meteorological visibility. This report also includes the results of a brief comparison among the ranges of duty cycle for the two-color, visual signal described in "Alternatives to Pyrotechnic Distress Signals; Laboratory and Field Studies."
