Thermal target system

摘要

A thermal signal generating device, including at least two parallel buss bars operable for carrying a current and a heating element having at least a first region and a second region. The heating element includes a plurality of horizontal traces and a plurality of vertical traces. Widths of each of the plurality of horizontal and vertical traces may be greater in a first region of the heating element than in a second region of the heating element, allowing for a gradient heat differential to be emitted by the heating element.

1. A thermal target system comprising:
a first conductive, resistive portion comprising first traces of conductive, resistive ink connected to a first electrical buss and a second electrical buss coupled to a source of electrical current to produce a first thermal image, each of said first traces spaced from each of said other first traces and each of said first traces extending from said first buss to said second buss; a second conductive, resistive portion comprising second traces of conductive, resistive ink connected to said first electrical buss and said second electrical buss coupled to the source of electrical current to produce a second thermal image, each of said second traces spaced from each of said other second traces and each of said second traces extending from said first buss to said second buss; and said first traces and said second traces having different thicknesses relative to each other such that said first conductive, resistive portion and said second conductive, resistive portion have different resistances relative to each other and such that said first thermal image is different from said second thermal image, wherein a combined first thermal image and second thermal image mimics a desired thermal signature; said first conductive, resistive portion and said second conductive, resistive portion bonded to a sheet to form a target to be releasably connected to an object.
