摘要
基于紫外辐射大气传输特性的紫外探测技术是一种新型成像检测技术，拓展了军事上可用的电磁频谱范围，得到了迅速发展。以光谱辐射特性及图像增强为基础，提出了一种紫外场景仿真方法。创建了目标和背景的红外场景仿真，推算目标模型中每个像素点对应的辐射温度；根据普朗克公式计算目标场景在紫外谱段的辐射出射度和图像灰度，对获得的紫外图像进行图像增强处理，最终获得实用的紫外场景仿真图像。结果表明仿真效果良好。
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.
