Abstract

A small target is a target which is far enough to a detector, and its image on FPA can’t be large enough to show its shape and size. In this situation, when a small target is detected by an infrared imaging single-band detector, we can only analyze it by the dispersion point or the subpixel image caused by it. The target discrimination can be impossible when it meets a smaller-sized target with higher temperature and a larger-sized target with lower temperature, because their image on FPA can be quite similar when they’re far enough. However, with the dual-band detection, we can figure out the temperature via dual-band ratio easily, without the information of distance and target size. Equivalent area can be also figure out during this calculation. The target discrimination can be achieved with the temperature and equivalent area known. And according to some priori knowledge, can we make those target recognized in a particular scene. This article briefly show the benefit of dual-band detection compared to single band detection.
