ABSTRACT:
A sheet of camouflage material is provided for concealing people and equipment from people or animals having a sense of color or geometric perception. The sheet has a plurality of alternating rows of straight-sided, upright V-shaped cuts with intermediate rows of inverted V-shaped cuts. The upright V-shaped cuts line up vertically in alternating columns with intermediate columns of inverted "V" cuts. Each shaped cut is comprised of a long straight incision and a short straight incision which intersect to form a triangularly-shaped point. The ratio of the lengths of the short incision to the long incision and the ratio of the spacing between points of the adjoining shaped cuts in a column and the length of the long incision are defined so as to produce a sheet of camouflage material which, when stretched, produces a three-dimensional effect with sharp points simulating grass or leaves with a height in the third dimension between three and four times the height of previous incised camouflage sheets. The increased height or increased third dimension improves concealment from radar. Controlled stretching of the sheet results in a particular and predictable see-through factor which is commensurate with the radar return. Less blades are necessary to incise the material and they are cheaper to build and cheaper to maintain.
