Abstract

Abstract In a thermal target suitable for live weapons fire, a resistive material is disposed between layers of insulation and screen like continuous electrodes. Portions of insulation are removed at predetermined locations to expose the resistive material and the continuous electrodes are fastened to the exposed resistive material. When an electrical potential is applied to the continuous electrodes the target emits thermal radiation in order to simulate a known thermal image for an infrared sighting device.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 67 words
A thermal target comprising: resistive material having at least first and second surfaces; insulating means disposed upon at least the first and second surfaces of said resistive material and having portions of insulation removed therefrom at predetermined locations; and continuous electrode means disposed upon said insulation means and fastened to at least the first and second surfaces of said resistive material for applying an electrical potential thereto.
Claim 2
Dependent Claim 67 words
A thermal target comprising: resistive material having at least first and second surfaces; insulating means disposed upon at least the first and second surfaces of said resistive material and having portions of insulation removed therefrom at predetermined locations; and continuous electrode means disposed upon said insulation means and fastened to at least the first and second surfaces of said resistive material for applying an electrical potential thereto.
Claim 3
Dependent Claim 26 words
The apparatus according to claim 1 wherein the portions of insulation removed from said insulating means are used to simulate the thermal image of an object.
Claim 4
Dependent Claim 18 words
The apparatus according to claim 1 wherein the insulation is removed from said insulation means in uniform sections.
Claim 5
Independent Claim 19 words
The apparatus according to claims 2 or 3 wherein said continuous electrode means are fabricated from electrically conductive screens.
Claim 6
Dependent Claim 19 words
