Abstract

For applications like missile warning and automatic target recognition, AIM is presently launching its new 3rd generation high speed dual-color module. The focal plane array (FPA) is a mercury cadmium telluride (MCT) 192x192 56micrometers pitch device in a dual-color mid wave (MWIR) design. The module provides spectral selection with temporal and spatial coincidence for both colors using a new AIM proprietary technology. The spectral bands presently selected are 3.4-4 and 4.2-5micrometers with a full frame rate of 870Hz. Prior to the new devices, a sequential multicolor MCT camera with broadband detector and spectral selection using a rotating filter wheel was developed and evaluated. Results are shown to demonstrate the capabilities of spectral selective detection specifically for clutter and false alarm suppression in missile warning applications. A new algorithm was developed to allow highly sensitive detection of missile plumes without any need for non-uniformity correction for long-term stable operation and maximum dynamic range. An outlook is given on new activities at AIM on dual-band devices. The dual-band approach combining mid wave (MWIR) and long wave (LWIR) detection is specifically useful in automatic target recognition. The application, existing devices and the design goal of the new dual-band device are discussed together with experimental results.
