This technical memorandum provides results of exercising the model in the form of approximately 850 plotted curves of range versus the ratio of target-to-background temperature difference to FLIR noise equivalent temperature difference. Range curves are given for three tasks (acquisition, classification and identification) for two classes of ships (destroyer and patrol boat) from two aspect angles (beam and bow/stern) for three aircraft altitudes (300, 4,000 and 12,000 feet) for three values of sea level absolute humidity (5.4, 14.0 and 29.7 grams per cubic meter) and for eight values of FLIR nominal resolution (ranging from 1.0 to 0.07 mrad). 收起
