【摘要】：掌握背景在椭圆轨道红外监视平台成像特性是开展红外图像数据处理的基础。首先,构建了椭圆轨道红外监视平台的几何投影模型和信号传递模型,给出了红外传感器的成像模型;其次,分析了平台姿态、背景本体相对运动、卫星轨道等因素对背景成像特性的影响,并推导给出了相关数学影响模型;最后,通过仿真试验验证了数学推导模型的正确性,并给出了背景成像特性的综合仿真结果。分析结果表明:椭圆轨道红外监视平台探测图像中,背景呈现出了新特性,对红外图像数据处理提出了新要求。
[Abstract]:It is the foundation of infrared image data processing to master the imaging characteristics of the background infrared monitoring platform in elliptical orbit. Firstly, the geometric projection model and signal transfer model of the elliptical orbit infrared monitoring platform are constructed. The imaging model of infrared sensor is given. Secondly, the influence of platform attitude, relative motion of background body and satellite orbit on the background imaging characteristics is analyzed, and the related mathematical model is derived. Finally, the correctness of the mathematical model is verified by simulation experiments, and the synthetic simulation results of background imaging characteristics are given. The analysis results show that the elliptical orbit infrared monitoring platform detects images. The background presents new characteristics, and puts forward new requirements for infrared image data processing.
