DEFINITION

Classification: 273/348.1

Including heating means (i.e., thermal target):

(under subclass 348) Apparatus wherein the target device includes means for increasing its temperature for the purpose of causing it to radiate thermal energy.

(1) Note. When viewed through a thermally-sensitive aiming or sighting means, a heat-radiating target device can be seen under conditions (e.g., darkness) when it is invisible to the naked eye.

(2) Note. The means occasionally is utilized to heat only selected portions of the target device, whereby the device can be given a "heat signature" which is peculiar to a particular kind of device or structure; e.g., a tactical vehicle such as a tank.
