Infrared Radiation Characteristic Analysis & Temperature Field Calculation of Ship Target Based on Radtherm

Facing the requirement of target detection and recognition of infrared imaging system, on the basis of considering completely of ship material, the model of thermal, boundary condition and environment, the infrared radiation characteristic of ship target is researched on particularly, And the calculation of temperature field model and the modeling of infrared radiance intensity are carried out of certain place, weather condition and different time with the help of Radtherm. The theoretic analysis of emulational image and the contrast of measured long-wave infrared image demonstrate the effectiveness and accuracy of the infrared radiation characteristic analysis of ship target and the calculation of temperature field in this paper.
