What does the acronym FLIR stand for?

The acronym FLIR stands for Forward Looking Infrared. This technology is widely used in various military applications, particularly in surveillance and targeting systems. FLIR systems utilize infrared sensors to detect and visualize thermal radiation, allowing operators to see in complete darkness and through obscurants such as smoke, fog, or dust.

Forward Looking Infrared is essential in both airborne and ground-based applications, as it enhances situational awareness and target acquisition capabilities. The ability to see heat signatures makes it invaluable for identifying vehicles or personnel even in low visibility conditions. The other acronyms listed in the choices do not refer to established systems or technologies associated with infrared sensing, which further supports the accuracy of Forward Looking Infrared as the correct definition of FLIR.
