ABSTRACT:
A target simulator device for the simulation of infrared targets as input to entrance optics. A voice coil of an audio loud speaker including a cone portion and two electrical input connections has a physical projection one end of which is coupled to the cone portion and the other end approximate to and in front of a shield aperture. A black body radiation source is placed behind the aperture and a frequency compensated amplifier electrically coupled to the input connections such that collimated signal-modulated black body energy that is proportional to the total range of frequencies input is observed by an infrared sensitive detector aligned with the radiation emanating from the aperture.
