| Popis: | This paper presents a preliminary set of results for the LOFAR High-Band Antenna (HBA) Array. The high signal-to-noise ratio and scan capability of the UAV-based measurement system allowed the array verification at both element and tile level. Such data could not have been obtained with astronomical sources. The reported results confirm both pointing angle and beamwidth of the HBA tiles from 120 to 180 MHz. |
