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。
In the simulation of infrared thermal imaging, a signal injection simulation method is proposed to generate the infrared thermal image detected by the shipborne photoelectric tracker in order to achieve high cost performance. The system consists of 6 interacting modules. The target, the background and the interfering radiation reach the sensor through the atmospheric attenuation. The atmospheric radiation and atmospheric attenuation are calculated with the LOWTRAN model. The mathematical model of the sensor is used to form the gray quantization rules. The entire 3D scene is generated by using OpenGL. With this system, the ability of the electro-optical tracker to identify and track targets can be evaluated in a lab environment, reducing the number of field tests.
