AIM
1. The aim of this agreement is to provide standardized technical criteria for the definition of nominal static range performance for thermal imaging systems to be used for ground targets seen from the surface or from slightly elevated positions, in order to compare the performance of different systems.
VALIDITY
2. There are many variables which affect the performance of thermal imaging systems. In order that different systems may be easily compared, a standard set of conditions need to be defined as a basis on which performance calculations can be made. "Nominal range performance" is the term applied to the range calculated under these, standard conditions. The standard conditions have been chosen to be reasonably representative of conditions experienced in the field.
The task considered is that of static performance, no search, where the target location is within the field of view of the device and the observer has infinite time to find the target.
The procedure described is only valid for thermal imaging systems where the MRTD concept is defined (e.g. for properly sampled systems) and only applied to ground targets seen from the surface or from slightly elevated positions.
The applicable spectral ranges are 3-5 μm or 8-14 μm, or parts of these ranges.
