A program has been developed that divide apparent areas in a RadThermIR simulation model and IR registration of a
platform in different temperature intervals. It offers the possibility to choose any number of temperature intervals as well
as the interval sizes. The calculation also provides statistical parameters such as mean temperature, median temperature
and standard deviation. In an IR registration, the object can automatically be identified. For complex objects and rare
views a manual method of indicating the objects can be used.
The program can be used during the design for IR signature control and verification once the design is completed. The
program is demonstrated by using a simulation model and IR images.
This paper presents the work on the detection of land mines using IR-images. Experiments have been performed where outdoor time series of IR contrast have been measured for wax filled antitank mines in sand and for real mines in a gravel road. For antitank mines in the sand box the contrast dependence of time lap between burial and measurement has been analyzed for a period of four months. The diurnal contrast variation of an anti tank mine buried for two and a half year in a gravel road has been calculated. Statistical correlation between apparent temperatures and weather parameters for different cases have been calculated. The purpose is to understand the origin of the contrast and to be able to predict the contrast at different times and under different conditions.
