This 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.

Abstract

This 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.
