Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper studies the monostatic radar cross section (RCS) simulation of a popular Unmanned Aerial Vehicle (UAV), DJI Phantom 2 Vision Plus in UHF band. The RCS (sigma) is evaluated when the plane wave is horizontally and vertically polarized. First, for a constant theta angle and a varying phi angle the results show that sigma is higher than the other polarizations, its highest value is found when _ phi= 0 or phi = 90_, meaning when the excitation is in front of the center of the blades. Second, for constant phi_and a varying theta, in this case also, sigma is higher than the other polarizations, its values are quite constant around -17dBsm with 2dBsm more when looking from the bottom or from the top (-15dBsm). These results give us an idea about the optimal position of the radar to get the highest value of the RCS of the drone.
