Paper Abstract

The temperature variation and the infrared detection probability of the ground target in desert was studied through simulative calculation. The model of temperature variation of the ground and the target was established, of which the ground temperature variation was simplified as a one dimensional transient heat conduct model and the heat equilibrium state of the target was hypothesized as two basic idealized types. Furthermore, the calculation formula of every radiation part such as the sun direct radiation and scatter radiation, atmosphere long wave radiation, atmosphere convective heat conduction, etc., were analyzed and established. Afterwards, the model was constructed and calculated using Comsol software. Finally, the infrared detection probability of the target was calculated using NETD of the infrared imager under the point target hypothesis.
