Abstract

Two separate technical developments are described: a long wave (7.5 to 11.2 micron) multi-spectral (5 bands) second generation thermal imager (HgCdTe, 288 by 4) and real time algorithm implementation using a datacube maxvideo image processing system. When combined these two technologies provide an enhanced imaging sensor with several unique features for improved multi-spectral performance; including scene based histogram correction, spatial filtering, and frame averaging. Image processing options are adjusted by the operator to adapt and optimize imagery for different scene conditions via real time feedback. The paper describes system hardware, software development, and laboratory measurements and field observations which demonstrate the impact of different processing strategies against dynamic scene backgrounds. Advantages of real time processing include an NETD/MRTD performance improvement by a factor of 3. The TAS 4X FW/datacube system provides the ability to observe the migration of small quantities of gas (SF₆) from stand-off ranges of several kilometers. Filtered imagery when combined with real time processing can provide a new level of imaging performance that can observe scene details unresolvable by other techniques.
