【摘要】 UV覆盖是光学综合孔径成像技术中一个关键环节,它决定于孔径阵列的排列情况,且影响到后续的图像恢复工作,所以,必须对UV覆盖进行优化,但优化标准目前尚未确定.本文利用统计的方法从研究图像频谱的高低频特性入手,从对不同方式下UV覆盖对后续的图像恢复造成的影响情况的分析比较,进行优化标准的初步研究与探讨.更多还原

【Abstract】 UV coverage is one of the key parts of optical aperture synthesis telescope technology.Since UV coverage is decided by apertures array and has an impact on the recovering of images,an optimizing process must be considered.The optimizing criterion needs to be clearly defined.Through an analysis and comparison of the effects of image recovering by using different UV coverage,some simple conclusions have been drawn and discussed.更多还原
