An External Calibration Method for Compensating for the Mutual Coupling Effect in Large Interferometric Aperture Synthesis Radiometers
Figure 2
The HUST-ASR antenna array; (a) the photo of the whole antenna and the partial feed array; (b) a 16-element minimum redundancy linear feed array which can simultaneously measure visibility at 91 contiguous spacings (including zero spacing) with just 16 antennas. According to this arrangement, a conjoined triple-horn structure has to be used at each end of the array because of the very close spacings which contribute much to the mutual coupling.
