ABSTRACT:
An infrared radiation signature generation system including an enclosed chamber (12), a reactor bed (24) for vaporizing a vapor precursor, a pressure source (16) for introducing the vapor precursor to the reactor bed (24), a valve (22) for controlling rate of flow of vapor precursor to the reactor bed (24), the temperature of the vapor being greater than the ambient temperature surrounding the chamber (12), and at least one manifold (32-33) for distributing the hot vapor to the interior (34) of the chamber (12) at a pressure higher than the ambient pressure. The wall of the chamber (12) is formed of material which allows percolation of vapor therethrough, the percolating vapor transferring heat to the chamber wall and causing a temperature rise therein whereby the chamber wall emits an infrared radiation signature in response to such temperature rise. There is a temperature transducer (40) interrelated with the wall of the chamber and responsive to the temperature thereof for generating a signal whose amplitude varies in relation to such temperature and a rate controller ( 44) responsive to the signal for controlling the generation rate of hot vapor to maintain the chamber wall at a steady state temperature whereby a continuous infrared radiation signature is generated.
