Finite Element Analysis Based Infrared Feature Analysis and Simulation of Ground Target

Calculation of surface temperature was the first and important step in ground target infrared feature analysis and simulation. Focus on it, this paper analyzed the factors which effect the ground target surface temperature based on the limit of finite difference in building target surface temperature field and integrated the theory of calorifics and infrared physics. Meanwhile, the building target surface temperature field model was established and calculated by finite element. Experimental results proved the correctness and validity of the model which provided in this paper.
