Abstract
This paper describes the last experimental results and studies of Safran telemetry ground antenna implementing Active Electronically Steerable Antenna (AESA) technology. Telemetry ground antennas play a key role in telemetry systems, by receiving data transmitted by the flying object and sending it to a ground system for data processing. The use of AESA technology allows for more precise targeting and tracking, making it ideal for high dynamic applications. The design presented in this paper is a 1-axis electronically steerable antenna, which is used for elevation axis while azimuth axis is mechanically driven. This S-band antenna is specifically intended for short to medium range telemetry and is able to handle high target dynamics. The paper presents the results achieved with a first prototype, at system level, with targets in real condition like rockets and LEO satellites. Moreover, beamforming shaping are likewise detailed in this paper in order to solve critical cases of propagation phenomena.
