Antenna Arraying Technologies and the Development in Deep Space Network

This paper introduces the principle and the development of the antenna arraying technology, and five basic antenna arraying schemes proposed by DSN are discussed here. All of the five schemes can combine the outputs of separate antennas that are observing a spacecraft-type signal. The major signal processing method used in FSC arraying scheme which can process with IF signals is studied, and the key technologies in Antenna Arraying, such as time-delay compensation, complex-weight evaluation and the best weight evaluation, are also studied here. Finally, the application of the antenna arraying technology and the future development of the technology used in deep space exploration and satellites communication is discussed.
