This figure of merit is strictly related to the single element sensitivity, which is difficult to measure using astronomical sources. On the other hand, the characterization of a low-frequency antenna inside an anechoic chamber is not straightforward down to 50 MHz. In this contribution a novel method to measure the sensitivity of a single LFAA receiving chain is presented. The proposed technique utilizes a micro Unmanned Aerial Vehicle equipped with a RF test source. A preliminary error budget analysis demonstrated that this technique is able to measure the sensitivity of a LFAA chain with high accuracy.STAMPAenConference paper10.1109/ICEAA.2017.80654932-s2.0-85035113285https://ieeexplore.ieee.org/document/8065634FIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
