把信息熵应用于成像系统中,用端到端的互信息评价图像成像系统,研究成像系统的干扰设计方法。模拟系统设计参数,计算机仿真分析了三种性质的干扰对成像系统的影响,做出了基于互信息量的干扰效果仿真曲线。这对于光电对抗装备的研制、开发和效能评估具有一定的参考价值。
By extending information entropy to imaging system, we assess the performance of image system according to its end-to-end mutual information. The jamming methods of imaging system are studied. Assuming several sets of system design parameters we analyze the influence of three kinds jamming by the way of computer simulation. Mutual information based computer simulation of jamming effect are demonstrated. This is important for the development and the evaluation of the optoelectronic equipment.
