| 摘 要： | 结合信息光学理论知识与合成孔径系统的基本成像原理,得出了三种类型子孔径排布方式下的光学调制传递函数(MTF)分布,分析其成像特性;利用MATLAB软件在不同孔径排布情况下模拟其成像退化结果;采用最大似然的R--L复原方法对成像结果分别进行复原。根据计算机理论模拟的结果,该方法有较好的复原效果,图像的清晰度有所改善,一些细节系信息也有所完善;其中三臂型的清晰度最好,复原结果最佳。

| Abstract: | Based on the theoretical knowledge of information optics and the basic imaging principle of synthetic aperture system,the optical modulation transfer function(MTF)distribution of three types of subaperture distribution is obtained,and its imaging characteristics are analyzed.MATLAB software was used to simulate the image degradation results under different aperture arrangement.The maximum likelihood R-L restoration method was used to recover the imaging results.According to the results of computer simulation,the method has a good recovery effect,the image clarity is improved,and some details are also improved.The three-arm model has the best definition and recovery results. |
