Paper Abstract

We utilize the Finite Element Model (FEM) and Finite Difference Time Domain (FDTD) numerical solution of the Electromagnetic wave propagation in the Short Wave Infrared (SWIR) and Long Wave Infrared (LWIR) bands in order to calculate the target radiance propagation and environment attenuation due to transmission, absorption and reflections in atmosphere and obstacles. We leave to traditional minimum resolvable temperature (MRTD) the model of the camera radiance collection (actual thermal sensitivity of the camera). The main advantage of the numerical propagation is that there is the possibility to model exactly the specific target shape and the specific environment (depending of the computational power) and calculate the residual temperature.
