Coating permitting a reduction of the signature is visible, infrared and radar of a target, in order to guarantee the mechanical strength of the lining

摘要

The present invention relates to a coating for the reduction of the signature of a target in the visible, infrared and radar, characterized in that it is constituted by a stack of layers (1 to 8) of materials which are isotropic and homogeneous at the frequencies considered, the electromagnetic waves received by the radar coating in the strips of the radar frequency determined (x, ka, w). This stack is optimized for the coating according to the invention appears globally relative to the outside as an absorbent material for the radar frequency bands considered, and optimized in order to guarantee the mechanical strength of the coating by applying to the layer (1), the more the surface of the coating, a minimum thickness determined. Applications: stealth in the range of frequencies is visible, infrared and radar.
