Abstract
The maximum detection range for an infrared system depends on the signal-to-noise ratio of the target. Calculation of the signal from an intrinsic infrared detector with a flat spectral quantum efficiency such as indium antimonide or mercury cadmium telluride is straightforward, and simplifications yielding closed-form solutions can be obtained. Schottky barrier diodes have a complex spectral quantum efficiency function because of the nature of hot carrier photoemission, leading to a complex function for both the signal and noise components. This paper derives a detection range equation for Schottky barrier staring sensor systems using this spectral relationship as well as other parameters unique to these diodes.
