Abstract
Abstract A system for augmenting the visual and radar characteristics of an airborne target wherein a light source is mounted within the confines of a target body and is adapted to emit a beam of light in at least one direction. A radar reflector is mounted within the confines of the target body forwardly of the light source, as viewed in the direction of travel of the light from the light source, with the radar reflector being substantially transparent to light and reflective to radar wavelengths.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A system for augmenting the visual and radar characteristics of an airborne target in a common sector comprising, a. an elongated target body, b. a visible light source mounted in line within the confines of said target body and adapted to emit a beam of light axially of said body in at least one direction, c. a radar reflector mounted within the confines of said target body coaxially with and forwardly of said light source as viewed in the direction of travel of light from said light source so that said radar reflector is in the path of light propogating from said light source with said radar reflector being substantially transparent to light from said light source and reflective to radar wavelengths.
Claim 2
Independent Claim
122 words
A system for augmenting the visual and radar characteristics of an airborne target in a common sector comprising, a. an elongated target body, b. a visible light source mounted in line within the confines of said target body and adapted to emit a beam of light axially of said body in at least one direction, c. a radar reflector mounted within the confines of said target body coaxially with and forwardly of said light source as viewed in the direction of travel of light from said light source so that said radar reflector is in the path of light propogating from said light source with said radar reflector being substantially transparent to light from said light source and reflective to radar wavelengths.
Claim 3
Dependent Claim
20 words
A system as defined in claim 1 in which said radar reflector is a metallic screen-like member of open mesh.
Claim 4
Dependent Claim
17 words
A system as defined in claim 2 in which said radar reflector comprises relatively flat screen-like members.
Claim 5
Dependent Claim
21 words
A system as defined in claim 2 in which said radar reflector is in the shape of a generally triangular trihedral.
Claim 6
Dependent Claim
22 words
A system as defined in claim 2 in which the mesh density of said screen-like member is approximately eight openings per inch.
Claim 7
Dependent Claim
24 words
A system as defined in claim 2 in which said screen-like member is formed of stainless steel wire of approximately .0045 inches in diameter.
Claim 8
Dependent Claim
19 words
A system as defined in claim 2 in which the openings in the mesh are approximately one-tenth radar wavelength.
Claim 9
Dependent Claim
35 words
A system as defined in claim 2 in which said light source and said radar reflector are mounted inline in a cylindrical portion of said body without changing the basic aerodynamic shape of the target.
Claim 10
Dependent Claim
39 words
A system as defined in claim 2 in which a turbine unit is mounted for rotation adjacent the rear of said target body and is operatively connected to an electrical generating unit which supplies power to said light source.
