摘要
在红外成像系统静态性能模型的基础上,利用运动传递函数分析了线性、正弦、随机3种运动形式对成像系统性能的影响,建立了动态性能理论模型.结合背景杂波对约翰逊准则的修正,利用计算机对动态性能模型仿真,仿真结果表明运动效应和背景杂波对系统现场性能的影响是明显的.
Abstract
On the basis of the IR imaging system static performance model, the effect of linear motion, sinusoidal motion and random motion on the system performance were theoretically analyzed with the motion transfter function. Additionally, detection criteria modified by background clutter was introduced, and dynamic performance model was established and simulated. The modeling result shows that the influence of motion and background clutter on the system field performance should not be ignored.
