摘要
合成孔径阵列技术是对射电天体进行微波成像的有效手段,利用合成孔径阵列技术对太阳进行微波成像,可以完成多微波段的太阳成像,更深层次地揭秘太阳的物理本质。在综合孔径成像技术中uv网格的划分对成像质量有重要的影响,在此对uv网格的划分进行了详细的研究,通过在Y字排列的天线阵列中选取5天线点,对模拟射电源进行成像分析,给出了成像质量与FFT变换速度之间的解决方法,对提高合成孔径阵列的成像质量有很大的帮助。
The Synthetic aperture array technology is an effective means of microwave imaging that observes radio stars. The uv mesh division in the synthetic aperture imaging technique has a significant influence on image quality. In this paper, the uv mesh division is studied. An imaging analysis of the simulation radio source is conducted by the selection of 5 antenna points in the Y-type antenna array and a solution between FFT conversion speed and imaging quality is given. The method has great help for improving the imaging quality of synthetic aperture array.
