Abstract
Low frequency aperture array technology requires advanced ad-hoc tools for performing antenna and array pattern characterization and instrumental calibration. A micro Unmanned Aerial Vehicle (UAV) mounting a radio-frequency transmitting system developed in Italy has demonstrated to satisfy the challenging characteristics of these tasks. Therefore, a measurement campaign by means of this UAV system has been planned to one Dutch station of the Low Frequency Array (LOFAR) with the main goal to improve the LOFAR antenna and array models. In preparation for this campaign, some initial tests applying the UAV system to one low-frequency antenna of LOFAR were performed in Italy. This contribution describes this measurement session and shows that the measured antenna gain patterns at different frequencies between 40 and 70 MHz agree very well with the electromagnetic models.
