Abstract. This paper discusses techniques for overcoming two problems associated with
detecting and classifying small targets in tropical environments on hot
sunny days. The first problem is associated with ground-based thermal
imaging through a turbulent atmosphere, rising up from the sunlit
hot ground. Of interest are ways of reducing the level
of apparent shape distortion and motion, and blurred edges in
thermal imaging. The second problem is the daytime detection of
targets in cluttered sunlit woodland. Targets dweling in the shadows
are obscured in scenes dominated by the sunlit foliage and
sunlit ground. A method of filtered thermal imaging suppresses the
sunlit and sun-heated features and provides a means of detecting
thermal signatures of shaded objects.
