ABSTRACT:
A generally flexible, quilt-like, broad band multispectral camouflage blat which embodies a matrix of commercially available laminated wide band, energy absorbing material which is precut into polygonal shaped panels to thereby effectively collectively absorb and suppress radar, heat and sound energy. The panels are either removably disposed or otherwise suitably bonded within complementary sized pockets in the blanket fabric and are oriented in a flexible grid-like arrangement. The blanket fabric, such as a KEVLAR nylon or the like, which by its very nature is impervious to water and many other contaminents, is further characterized by a low reflectivity at microwave radar frequencies, and may be visually camouflaged for different tactical environments. The flexibility provided by the grid-like arrangement is compatible with the need to generally convexly conform to the shape of the object being protected or to secure to an intermediate framework in a suitable non-dihedral/trihedral planar angle manner to preclude retroreflection by reentrant geometries of the blanket when used at higher frequencies where it will not absorb energy waves. The same flexibility also enables it to be readily folded for compact stowage.
