为探索红外干扰的定量测定方法以及确定参数对红外背景干扰值大小的影响,分析了大量红外背景图像数据,并以象元电平为单位,对红外背景图像内的干扰噪声进行了计算。经过空间滤波处理和非滤波两种情况计算了图像的光谱密度,获得了关于红外背景图像的空间频率构成的信息,把计算出来的干扰值输入数据库取出多组数据绘图,确定了参数量对干扰电平的影响。
In order to explore the quantitative determination of infrared interference and determine the influence of parameters on the interference of infrared background, a large number of infrared background image data were analyzed. The interference noise in the infrared background image was calculated by pixel level. The spectral density of the image was calculated by both spatial filtering and non-filtering, and the information about the spatial frequency of the infrared background image was obtained. The calculated interference value was input into the database to take out multiple sets of data plots, The impact of the level.
