The software package of LOWTRA7 was used to simulate and generate the dynamic infrared images of targets and the background, which supplied a data base for the guidance and fire control.

Typical applications include missiles guidance, aerial survey, infrared hunting and tracing system, custom suppress smuggling, salvage equipment and forest fire control etc.

For infrared surveillance system, it is most difficult that the measurements are only angles not distance, which makes target location of fire control system be difficult to realize.
