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.

A camouflage material for covering and stretching over a structure to prevent visual and radar detection thereof, said camouflage material being formed of a planar sheet of material having top and bottom surfaces, a vertical dimension and a horizontal dimension substantially perpendicular to said vertical dimension, and a plurality of spaced apart horizontally aligned rows and vertically aligned columns of V-shaped cuts therethrough, each V-shaped cut comprising two straight unequal in length cuts defining a triangular member hinged about a base angularly disposed with respect to the horizontal dimension of the sheet and having a central axis bisecting the angle formed between the legs which axis is substantially aligned in the vertical dimension of said sheet, alternate rows of V-shaped cuts being inverted with respect to intermediate rows of V-shaped cuts with the inverted V-shaped cuts being further aligned in alternate vertical columns intermediate vertical columns containing the upright V-shaped cuts, the longer length cut of each triangular member having an end adjacent to the end of the shorter length of cut of the adjacent triangular member, the vertical component of the longer length of cut being from 12% to 25% greater than the vertical component of the shorter length of cut of each V-shaped cut whereby stretching said material in a direction transverse to the rows of V-shaped cuts extends the apexes of the triangular members in one row upward out of the plane of the sheet away from said top surface with the next adjacent row of cuts extending the apexes of the triangular members downward out of said plane away from said bottom surface, said V-shaped cuts projecting from said surfaces substantially straight relative to the plane of said sheet to prevent viewing of both of said surfaces simultaneously from one side of said sheet.
