A NOVEL RAM CONCEPT FOR SIMULTANEOUS CONTROL OF IR SIGNATURES

A NOVEL CONCEPT IS PROPOSED TO DEVELOP COATINGS WITH DUAL RADAR AND THERMAL SUPPRESSION CHARACTERISTICS. THE CONCEPT EMPLOYS WELL KNOWN TECHNIQUES USED FOR RADAR ABSORBING COATINGS AND COMBINES THEM WITH TECHNIQUES FOR PRODUCING LOW EMISSIVITY SURFACES IN THE INFRARRED WAVELENGTHS IN A WAY IN WHICH TOTAL COMPATIBILITY IS ASSURED. VARIOUS COMBINATIONS OF MATERIALS DEMONSTRATING THE APPROPRIATE PROPERTIESAND THE REQUIRED COMPATIBILITY ARE AVAILABLE. MATERIAL TYPE AS WELL AS GEOMETRY AND CONFIGURATION CAN BE USED AS VARIABLES FOR PERFORMANCE OPTIMIZATION. IN ADDITION TO THE REQUIRED RADAR ABSORBING PROPERTIES AND LOW EMISSION OPTICAL PROPERTIES, IT APPEARS THAT AN APPROPRIATE MATERIAL SELECTION MAY ALSO PROVIDE COATINGS CAPABLE OF BEING APPLIED IN ENVIRONMENTS OF MODERATE AND ELEVATED TEMPERATURES. DURING PHASE I, AN EXAMINATION WILL BE MADE OF THE MATERIAL PARAMETERS AND THE GEOMETRIC PARAMETERS TO DETERMINE WHAT COMBINATION OF PROPERTY TYPES AND GEOMETRIES SHOULD BE EMPLOYED TO PRODUCE COATINGS POSSESSING OPTIMIZED DUAL RADAR AND THERMAL SUPPRESSION CHARACTERISTICS AS WELL AS LOW EMISSIVITIES IN THE VISIBLE SPECTRUM. MODERATE TO ELEVATED TEMPERATURE PERFORMANCE WILL ALSO BE ONE OF THE OBJECTIVES.
