has a conductive path deposited substantially across its surface area the window geometry and the conductive paths provide rf energy signature management rfsm resulting in a low rf energy cross section the window 100 in the exemplary embodiment has a first surface 102 and a second surface 104 a flat surface 106 substantially a table is provided at the thickest portion of the window 100 and is substantially parallel to the second surface 104 over its area a first leading edge 110 is located at the proximal end 112 of the window 100 substantially along the centerline and provides an aerodynamic or similar function a trailing edge 114 is provided at a distal end 116 of the window 100 and has a shallow sloped surface covering substantially the distal u2153 of the first surface 102 fig2 is a top view of the first surface 202 of the window 200 in the exemplary embodiment shown the window 200 has seven segments that are mitered edged sapphire elements joined together at the edges to practice a window seven segments are not required any combination of segments can be used that combine to produce the desired angles of the panes and the angles of the edges of the window the angles of panes and edges that define the window are manufactured and assembled so as to provide acceptable reduction in the return of a desired bandwidth of energy of a threat radar such as rf energy in azimuth and elevation and improved field of regard for example in aerodynamic applications air flow and turbulence can deleteriously impact radar signature of an otherwise low radar cross section the.
