Abstract
The notion of modulating an aircraft's infrared (IR) signatures based on the anisotropic emission behavior of aircraft skin is proposed. The integrated IR transmission model from aircraft to detector is established by the matrices. IR signature azimuthal profiles and gray-level images are used to evaluate the effectiveness of the IR modulation technique. The results show that as the hemispherical emissivity remains constant, changing the angular emission behavior of aircraft skin can modulate the directionality and contrast characteristics of IR signatures.
