AGREEMENT
3. Participating nations agreed that the criteria established in the following paragraphs will apply when stating nominal static range performance for thermal imaging systems in relevant military and technical documents.
4. Participating nations further agree to state ranges in the following form:
a. Nominal static detection range, in kilometres.
b. Nominal static recognition range, in kilometres.
c. Nominal static identification range, in kilometres.
The transmission conditions (good or limited) and the relevant field of view of the system, in degrees or milliradians shall be stated for each range, and the method of obtaining the minimum resolvable temperature difference (MRTD) (measured or calculated), shall be specified.
NOTE 1 : The operational definitions of detection, recognition and identification can be found in the related document.
NOTE 2 : Depending upon the type of system only one or two of the three specified ranges might be appropriate.
DETERMINATION OF THE NOMINAL STATIC RANGE PERFORMANCE
5. The procedure needed for the calculation of the nominal static range is included in Annex A. The detailed parameters for the calculation are specified in paragraph 6.
DETAILED PARAMETERS
6. The nominal static range performance for thermal imaging systems will be determined from the averaged MRTD (see Annex B) and under the following conditions:
- target size: 2.3 × 2.3 m;
- oT。: 2K between target and background (related to a black body temperature of 288 K);
