Ultraviolet detecting technology, based on the atmospheric transmission characteristics of ultraviolet radiation, is a new imaging technique. It broadens and develops the available electromagnetic spectrum in military field. Based on spectrum radiation characteristics and image enhancement, a new ultraviolet scene simulation method is proposed. The infrared scene simulation of target and background is created. The radiation temperature of each pixel in the target model is calculated. The corresponding radiation exitance and image grayscale in ultraviolet spectrum are acquired by using Plank formula. By introducing image enhancement, practical ultraviolet scene simulation images are obtained. The experimental results show that the simulation effect is good.
