The detection and discrimination of man-made objects in a terrain or sky background has long been a challenge to the military. Conventional infrared (IR) systems suffer from poor spatial resolution and have a difficult time imaging targets when there is little or no thermal variation ((Delta) T) in the scene. These applications, as well as applications such as aircraft ice detection, can benefit from an imaging system that can overcome these and other limitations. In this paper an enhanced IR imaging sensor which overcomes the above shortcomings is described. Its advantages are detailed and accompanied by numerous experimental examples. The focus in this paper is on the performance of the sensor, and the benefits derived therefrom, not on sensor processing theory.
