Horizons Technology, Inc. (HTI) proposes to examine current and developing masking technologies in the microwave, infrared and visual spectral regions to design a camouflage system which can be applied to 3rd generation hardened aircraft shelters in the european and pacific theaters. The research effort will focus on developing a series of approaches to signature reduction of the steel framework, doors and aprons of the shelters, costing those efforts and, through various modeling techniques, verifying the efficacy of the proposed approaches. Through compatibility analysis, HTI intents to optimize the mixture of approaches derived and recommend a primary design. Phase I will review existing and developing technology, create a full compatible design meeting the unique structure requirements, and analyze the feasibility of the recommended design. Phase II will provide design verification through component testing, modeling applications and full scale prototype field testing; all leading to a design acceptable for service-wide application.
