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.
