摘　　要：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。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.
