| 摘 要： | 天基红外成像预警大多属于点目标探测,如何在复杂背景及随机点噪声条件下实现点目标的有效探测和跟踪是天基红外预警技术重点研究内容。研究了新型前置栅网滤波热成像理论,分析了基于前置栅网滤波形成特定衍射斑对天基红外成像点目标探测的影响,利用Matlab对栅网的滤波效果进行了模拟仿真,所得仿真图像与实验图像的衍射强度分布具有较好的一致性;并在相同点目标能量条件下,对点目标及其前置栅网滤波衍射图案进行了人眼视觉探测实验,初步分析表明了其对于点目标探测和跟踪的有效性,为进一步研究和发展高性能的天基红外成像技术提供了一种新途径。

| Abstract: | Space-based infrared system(SBIRS) for early warning usually uses point target detection.Obviously,effective detection and tracking of point target in cluttered background is not easy to realize.The method of solving this problem is one of the key research directions at present.The imaging principle of thermal imaging system with a front wire grid filtering was studied,and the influence of its diffraction spot on the point detection of SBIRS was analyzed.Then,the effect of wire grid filtering was simulated ... |
