Paper Abstract

This paper presents signal processing techniques used in a new FLIR design to improve the minimum resolvable temperature, to increase the dynamic range, and to provide additional new features. The techniques include analog edge enhancement, low frequency amplitude limiting, digital filtering, automatic gain and level control, and electronic zoom. The system uses an eight- channel SPRITE detector and, as a result, all analog processing must be replicated in each channel. This design uses adequate analog processing to allow the use of eight-bit scan conversion and digital processing without sacrifice of dynamic range. The result is a highly effective tradeoff between function and cost.
