摘要: 地基红外经纬仪是测量空间军事和科学目标红外数据的重要手段之一。随着现代武器技术在隐身上方面的快速发展，面源体测量越显重要，而辐射亮度是面源红外作战的关键性指标。因此研究可靠的面积分析方法和辐射亮度计算方法对测试航空目标的隐身性能以及研制面源红外假目标具有重要的意义。本文提出一种简单可靠的面目标的提取方法，并利用该面源提取方法在某ϕ600 mm口径的红外经纬仪上进行辐射测量，测量数据经大气修正后将与标准亮度值进行比较。实验结果表明，利用本文提出的方法反演的辐射亮度的最大误差为11.38%，均方根误差为7.36%。Abstract: The ground-based infrared theodolite is one of the most important means of measuring infrared data of military and scientific targets in space. With the rapid development of modern weapons technology in stealth, the measurement of surface target is becoming more and more important and the radiation brightness is a key indicator of surface type infrared combat. Therefore, it is of great significance to study area analysis method and radiance calculation method to test the stealth performance of the aviation target and to develop surface type infrared false target. In this paper, a simple and reliable method for extracting surface targets is proposed. By this method, radiation measurement is performed on a 600 mm aperture infrared theodolite. The measured data is compared with the standard brightness value after atmospheric correction. The experimental results show that the maximum error of the radiance inversion is 11.38% and the root mean square error is 7.36%. The experimental results show the effectiveness and reliability of the measurement method.
