摘要
在红外热像的生成仿真中,为达到高的性能价格比,提出了一种信号注入式仿真方法来产生舰载光电跟踪仪所探测到的红外热像.该系统由6个相互作用的模块组成.目标、背景和干扰的辐射经过大气衰减到达传感器,用LOWTRAN模型计算大气辐射和大气衰减,通过建立传感器的数学模型形成灰度量化规则,用OpenGL生成了整个三维场景.通过该系统,可以在实验室环境下评估光电跟踪仪识别和跟踪目标的能力,从而减少了外场试验的次数.
Abstract
In the generation of infrared image, a method based on signal injection is presented in order to attain a high performance-price ratio. It consists of six interacting modules. The radiance of target, background and interference arrives at the sensor after it is attenuated by the atmosphere. The radiance and attenuation of the atmosphere are computed with the LOWTRAN model. With the mathematical model of the sensor, the scaling principle of converting the radiance to the gray-scale is built. The whole 3D scene is rendered with OpenGL. By this system, the ability of recognizing and tracking target can be evaluated in the laboratory. Therefore the outfield experiments can be reduced.
