Abstract

A gravitationally balanced reflector antenna with minimized spun inertia has recently been considered for remote sensing applications. The back‐to‐back reflector antenna structure is used to generate two off‐nadir scanned beams. In particular, to overcome the large azimuth displacement between Tx/Rx events due to the high spinning rate and high orbit altitude of the antenna, a customized integrated twin‐horn feed with partially overlapped corrugation is designed to transmit and receive signals, respectively. Simulation and measurement results of the twin‐horn feed agree very well. The simulated far‐field pattern of the reflector antenna matches well with the design goals. © 2009 Wiley Periodicals, Inc.
