Abstract
For long range detection of low observable targets at sea infrared search and track systems are needed with high sensitivity. This goal can be achieved by integrating two-dimensional focal plane arrays into large optics. We have performed tests with such an integrated system in the 3 - 5 micrometers band, by using an InSb array with a 30 cm aperture. Besides this infrared band a scanning 10 micrometers detector is also placed in the optics for reference purposes. With the high frame rates (25 Hz) of present day FPAs we also have a powerful tool to reject background clutter (by temporal analysis). With this system we performed observations of atmospheric effects such as scintillation, under different atmospheric conditions. The gathered data were analyzed in a preliminary way, and both bands are compared.
