光学合成孔径成像原理及图像复原技术

Imaging and Image Restoration of Optical Synthetic Aperture Systems

根据光学合成孔径系统成像原理,利用傅立叶光学理论得出了合成孔径系统的点扩散函数(PSF)和光学传递函数(OTF),从这两个参数分析了合成孔径成像系统的性能;给出了使用维纳滤波算法进行图像复原的方法。分析和实验结果表明,用光学合成孔径系统和图像复原技术完全可以达到单个大孔径的成像观测效果。

Based on the imaging principle of Optical Synthetic Aperture Systems this paper expounds the two parameters, PSF and OTF, utilizing Fourier Optics, and with these two parameters this paper analyzes the performance of Optical Synthetic Aperture Systems, and gives the method of image restoration with Wiener filtering. The analysis and experimental results show that it is feasible to use Optical Synthetic Aperture Systems and imaging restoration technique to achieve an imaging observation effect equivalent to that of single large aperture.
