The Low Observable Challenge Now You See It...Now You Don't Low Observable Material Spectro Dynamic Systems produces electromagnetic absorbers which are used in applications requiring precise signature control over a wide frequency spectrum. If your requirements fall within the low gigahertz range to the far infrared range, SDS can supply materials in the form of very lightweight paints, tiles, coatings, fabrics and nets. Tailored For Your Challenge Generally, SDS provides a system design for a specific platform to defeat sensors operating at frequencies most likely to be encountered by the platform. Whether for broad attenuation over a wide frequency range, or high attenuation at a specific frequency, SDS can design a system to increase the survivability of the platform. The availability of different material forms enhances the performance of the system by utilizing synergistic effects between the different materials and allows for retrofit designs to increase current platform performance without re-engineering the platform. In addition, true multispectral coatings can be designed to provide signature control in the microwave, millimeter wave, infrared, and visible spectrum regions. Tiles, Paints, Fabrics, Nets...And Much More Spray-on coatings are available in epoxy and polyurethane binders and achieve properties similar to those of glue-on tiles at the same weight. Fabric absorbers are supplied as single or multi-layer constructions depending on the requirements. Weights as low as 0.1 pounds per square foot have been effectively used in field applications. Lightweight nets incorporating radar absorbing or radar scattering materials are available and are designed to deny identification of platforms behind the net over the 1 to 96 Ghz frequency range. These nets typically weigh about 20 grams per square foot or less and have an open weave structure allowing light and air for ventilation to easily pass through. IR...Radar...Or Both SDS also produces special infrared absorbing coatings which are effective from the near to far infrared region. These materials may be incorporated over radar absorbers to yield multi-spectral combination absorbers. Infrared absorbing coatings are supplied as spray-on paints and on fabrics. Infrared absorbing coatings are as thin as 3 mils and weigh as little as 4 grams per square foot. SDS radar absorbers are unique because of their low weight, toughness and ability to absorb strongly at off-normal angles. SDS control coatings are also special because of their diffuse surface characteristics which eliminate "glint." Utilization of these materials requires experience in the design and performance measurements of low observable platforms. In some cases a collateral SECRET or above classification is needed to obtain more detailed performance specifications for these materials.  CAMTECH Camouflage Technology.  PO Box 1169 Newport Beach NSW 2106 Phone - +612 9918 7238 Fax: +612 9918 4844 http://www.camouflage.com.au   What's New at SDS.
