红外焦平面阵列探测器空间采样效应会对红外图像效果产生影响,为提高仿真红外图像的置信度,在信号注入仿真中需要对采样效应进行模拟。通过深入分析空间采样效应机理,建立了采样效应的数学模型,分析了分辨率的变换过程。利用基于图像像素处理的方法从空域上对红外仿真图像叠加空间采样效应。仿真实验表明,叠加了红外焦平面阵列探测器空间采样效应的红外仿真图像置信度明显提高,可作为重要环节提高红外成像仿真整体的置信度水平。
Infrared focal plane array detector spatial sampling effect will have an impact on the infrared image effects, in order to improve the confidence of the simulation of infrared images, signal injection simulation in the sampling effect needs to be simulated. Through in-depth analysis of the spatial sampling effect mechanism, a mathematical model of the sampling effect is established, and the transformation process of the resolution is analyzed. Image Spatial Overlaying Effects on Infrared Simulation Images from Spatial Airspace Using Image Pixel Processing. The simulation results show that the confidence of the infrared simulation images superimposed by the spatial sampling effect of the infrared focal plane array detector is obviously improved, which can be used as an important step to improve the overall confidence level of the infrared imaging simulation.
