深空网中的天线组阵技术及其发展

Antenna Arraying Technologies and the Development in Deep Space Network

依据天线组阵技术的基本原理及其在深空网中的发展,介绍了深空网中的5种天线组阵方案,研究了在信号中频进行组阵的全频谱合成方案以及天线组阵技术中的时延补偿、复权值估计算法和最佳权估计算法等关键技术,讨论了天线组阵技术的应用以及在未来深空探测和卫星通信中的应用前景。

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.
