Abstract
Abstract Pivotable, reflective target elements are used to reflect infrared radiat from blackbody sources and transmit the radiation toward infrared-detecting device to test the capability of the device to detect patterns of infrared radiation under dynamic field environment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
An infrared target generator comprising: a hollow housing having a top and a bottom, said top being transparent to infrared radiation; first and second blackbody sources disposed in parallel within said housing and diametrically opposed to each other, said blackbody sources each having a front end and a rear end; a planar array of rotatably mounted reflective elements positioned between said blackbody sources to reflect radiation from said blackbody sources outwardly through said top of said housing, a suitable means for rotating said reflective elements and a means for empowering said blackbody sources.
Claim 2
Dependent Claim
93 words
An infrared target generator comprising: a hollow housing having a top and a bottom, said top being transparent to infrared radiation; first and second blackbody sources disposed in parallel within said housing and diametrically opposed to each other, said blackbody sources each having a front end and a rear end; a planar array of rotatably mounted reflective elements positioned between said blackbody sources to reflect radiation from said blackbody sources outwardly through said top of said housing, a suitable means for rotating said reflective elements and a means for empowering said blackbody sources.
Claim 3
Dependent Claim
36 words
A target generator as set forth in claim 1 wherein the plane of said array is adjacent to said front end of said first blackbody source and to said rear end of said second blackbody source.
Claim 4
Dependent Claim
54 words
A target generator as set forth in claim 2 wherein each of said reflective elements is mounted for rotation independently of rotation of any other element in said array and is first position suitable for reflecting radiation from said first blackbody source and second position suitable for reflecting radiation from said second blackbody source.
Claim 5
Dependent Claim
26 words
A target generator as set forth in claim 3 wherein the plane of said array intersects the planes of said blackbody sources at approximately 45 degrees.
Claim 6
Dependent Claim
24 words
A target generator as set forth in claim 4 wherein said reflective elements are identical and each element is longer than it is wide.
Claim 7
Dependent Claim
21 words
A target generator as set forth in claim 5 wherein said housing provides insulation to said blackbody sources from external environment.
