In order to simulate infrared radiance of targets outdoors  in this paper we propose a new outdoor simulation method on the basis of heating the cloth by electricity. There are two major contributions in the paper. Firstly  uneven distributing of temperature field of the cloth surface is considered and the long-wave thermal imager is used as a link of the temperature control system. On the basis of many experiments  the expression is concluded about the relation of the temperature obtained by the lone-wave thermal imager and the temperature obtained by the temperature control system and the environmental temperature at the experimental scene. Secondly  the influence of the environment at the experimental scene on the infrared radiance of the cloth surface is thought over. Thanks to two measures above  simulation precision of infrared radiance is made much better. The results of many outdoor experiments demonstrate the performance of the proposed approach. 2009 SPIE.
