Paper Abstract

The space heat flux that the spatial balloon decoy gets is calculated in the appropriate coordinate system and the earth heat flux is calculated accurately with the use of the unit hemisphere method. The surface temperature distribution of the balloon decoy is got by solving the transient heat balance equations with the use of the finite element software, ANSYS 10.0. On the basis of the solved surface temperature distribution, taking the balloon decoy as a point object, the spatial distribution of infrared radiation intensity in 3~6um and in 6~16um is calculated. Finally, the differences of the surface temperature distribution and the infrared radiation intensity spatial distribution between the spatial balloon decoy got in this paper and a spatial target got in our previous work are compared and analyzed in detail. The research results of this paper have referential value on infrared automatic target recognition (ATR) of spatial targets.
