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.
