一种用于深空网天线组阵的基于归一化权的Matrix-Free Power Method

内容简介：对深空网天线组阵中的几种信号相关算法作简要介绍,重点研究无需形成矩阵的幂的方法--Matrix-Free Power Method.通过理论分析,提出一种改进算法,即基于归一化权的Matrix-Free Power Method.理论计算和软件仿真结果均表明,基于归一化权的Matrix-Free Power Method信噪比合成性能略优于原Matrix-Free Power Method.

Abstract：Several Correlation algorithms of the antenna arraying in DSN (Deep Space Network) are introduced in this paper. The emphasis is on the Matrix-Free Power Method. An improved algorithm is put forward which is called normalized-weight -based Matrix-Free Power Method. The comparison between the Matrix-Free Power Method and the improved algorithm is made during analysis, theory calculation and simulation. The results show that the normalized-weight-based Matrix-Free Power Method has a better combination SNR than the Matrix-Free Power Method.
