Abstract :
The design and testing of a 13-meter antenna system are summarized. The ground station antenna was designed for reception and tracking of signals from the ERS-1 satellite. The antenna employed a dual-shaped reflector geometry to achieve high efficiency and hence G/T (figure of merit). The system performance of the antenna was excellent. The predicted and measured figures of merit (G/T) were 35.5 dB/K and 35.0 dB/K at an elevation angle of 5/spl deg/, respectively. The active crosstalk correction scheme made for excellent system tracking performance.<>
