Abstract

Improvements in infra-red (IR) sensor sensitivity have resulted in background clutter becoming a limiting factor for target detection. The extreme IR clutter intensities which occur following detonation of nuclear weapons is a major limitation to target detection capabilities. This paper investigates improvements in the signal-to-clutter ratio provided by simple two-dimensional spatial filtering of IR detector array data. The difference in the spectra for natural and nuclear background clutter require different filter parameters to provide optimal performance.
