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。
According to the principle of optical synthetic aperture imaging system, the PSF and OTF of synthetic aperture system are obtained by Fourier optics theory. The performance of synthetic aperture imaging system is analyzed from these two parameters. Wiener filtering algorithm using image restoration method. The analysis and experimental results show that the imaging performance of a single large aperture can be fully achieved with the optical synthetic aperture system and the image restoration technology.
