Abstract

After some 30 years of research, infrared (IR) technology has evolved to a full valued science, caused by the development of new detector materials in particular and by low noise micro electronics in general. Initially requirements for research were mainly defined by scientific organisations and the Military. After a short general introduction to the subject, attention will be given to the characterisation of IR signatures along the lines of model development, to the definition of involved parameters and measurement methodology. After this overview, the topic of 'thermal variation in a natural land background' , which has a growing interest at the moment , will be treated. Especially, time will be devoted to discuss techniques to characterise the thermal behaviour of natural background elements by means of statistical evaluations of point radiometer data, collected over a long measurement period. Next to the point measurements attention will be given to the radiance variation (thermal clutter) in an image, i.e. the (time varying) distribution of IR sources irj position and time.
