使用单组远场无相位数据和类似填字的处理的反射器天线表征和诊断
Reflector Antennas Characterization and Diagnostics using a Single Set of Far Field Phaseless Data and Crosswords-like Processing
摘要：
我们介绍和讨论了一种新的方法，相位恢复的连续孔径源辐射的领域具有圆形的支持，这是在许多应用中，包括反射面天线的形状变形的检测的兴趣。该方法是基于实际的2-D问题分解成一些1-D相位检索问题沿直径和同心环的可见光谱的一部分。特别是，1-D的问题，有效地解决了使用频谱分解方法，而在交叉点的歧视参数允许完成检索的2-D复杂的字段。建议的程序，这只需要一个单一的远场振幅，利用到目前为止未开发的字段属性，它是在反射器孔径字段进行评估。
英文摘要：
We introduce and discuss a new approach to the phase retrieval of fields radiated by continuous aperture sources having a circular support, which is of interest in many applications including the detection of shape deformations on reflector antennas. The approach is based on a decomposition of the actual 2-D problem into a number of 1-D phase retrieval problems along diameters and concentric rings of the visible part of the spectrum. In particular, the 1-D problems are effectively solved by using the spectral factorization method, while discrimination arguments at the crossing points allows to complete the retrieval of the 2-D complex field. The proposed procedure, which just requires a single set of far field amplitudes, takes advantage from up to now unexplored field properties and it is assessed in terms of reflector aperture fields.
