Obscurants for Infrared Countermeasures
Abstract
The advent of imaging seekers in the 3-5 microns and 8-12 microns bands poses a new challenge in the area of infrared countermeasures. The next generation of seekers will be based on arrays that will provide me designer with a wide range of options for discriminating between enemy targets, friendly craft, and decoys. Area-extensive infrared countermeasures will be necessary to defeat these new seekers. One effective component of these countermeasures will be infrared absorbing particles, obscurants, essentially removing the original target from the imager's field. Our primary experimental concern in this study is to screen potential infrared obscurants as to their effectiveness, ease of deployment, chemical inertness, availability, cost, and environmental effects. Theoretical models that differentiate between scattering and absorption are also developed, and the results are compared to experimental measurements of extinction cross sections.
