Abstract
To model the thermal-vision images of terrestrial objects having internal
low-power heat sources and forced ventilation of the compartments, as well as to
increase the accuracy of the modelling in the absence of internal heat sources, it is
proposed to calculate the temperature regime of the objects, taking into account their
thermal balance with the environment. It is shown that, depending on the state of the
environment, the air temperature inside an object with no internal heat sources can be
either higher or lower than the atmospheric temperature, substantially affecting the
temperature contrast of the objects with the underlying surface in these cases.
