Accurate knowledge of initial complex excitation coefficients for phased-array elements is essential to ensure accurate array performance. In the literature, many array calibration algorithms have been proposed for this purpose, which generally requi

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 d
