Abstract : Three 120 line common-module FLIR (Forward Looking Infra-Red Imaging) units were tested on medium endurance cutters to ascertain how well they support Coast Guard law enforcement and search requirements. Large ship classification ranges varied from 3 to 13 nmi, depending upon the absolute humidity of the air path. Ranges for identifying the class of boats as fishing vessels were from 2 to 13 nmi, and the range for observing men on deck was 1 nmi. Identification and classification ranges were typically less than the desired 10 nmi and 5 nmi, respectively. A study of the utility of the NVS-500 night scope showed that its utility is limited to viewing objects having no visible lights. A further study directed toward alleviating the limitations of these instruments is recommended.
