Impact of radomes shapes on Direction of Arrival estimation, simulations and measurements
This paper presents the impact of different radome shapes on the direction of arrival (DoA), studied using simulations and measurements. For our study, four radomes, half-sphere, planar, Von Karman and tangent ogive, were designed using PLA 3D printing. DoA measurements without and with each radome were carried out. A platform, called SAMBA, dedicated to radar application is used for these measurements. Considering differential measurements, the direction of arrival is obtained directly without measuring S-parameters or radiation patterns. The measurements are compared with HFSS simulations, taking into account DoA estimators based on amplitude comparison.
