利用美国陆军TARDEC热图象模型(TTIM)和大气透射比模型(LOW-TRAN7),对中波(MW)和长波(LW)波段红外摄象机模型进行图象比较。对达到现代工艺水平的凝视焦平面列阵(FPA)、通用组件扫描前视红外(FLIR)和扫描双波段敏感器进行模型化。利用TTIM模型演示了各摄象机的成象性能以及在两个波段中大气所引起的退化。在北半球环境,雨天和雾天中模拟了大气对图象的退化程度。
An image comparison of the MW and LW band infrared camera models was conducted using the TARDM and LOW-TRAN7 models of the U.S. Army. Phased-Focal Plane Array (FPA), Common Component Scanning Forward-Looking Infra-Red (FLIR) and Scanning Dual-Band Sensing to modern state of the art are modeled. The TTIM model is used to demonstrate the imaging performance of each camera and the degradation caused by the atmosphere in both bands. In the northern hemisphere environment, rainy days and foggy days, atmospheric degradation of the image was simulated.
