Abstract EN
The efficiency of a reflector antenna highly depends on its surface shape.
In order to ensure a good convergence, the conventional phase retrieval based shape detection schemes require that several far-field intensities be scanned, focused, or defocused.
For large reflector antennas, the scanning process is time consuming.
This paper proposes a new shape detection method that requires only single far-field intensity.
Unlike existing shape detection methods, it retrieves both the amplitude and the phase, based on the fact that a deformed shape causes change not only in the aperture phase but also in the aperture amplitude.
Through even-odd decomposition analysis, it is found that in the case of small and smooth deformation, “odd-phase” and “even-amplitude” can be directly recovered from one focused far-field intensity.
This leads to the recovery of both the odd and the even parts of the antenna surface shape simultaneously.
By combining amplitude retrieval and phase retrieval, this work achieves for the first time the shape detection with only one scan.
