摘　　要：盲源分离技术是基于信号统计特性的信号处理技术，星载相控阵调零技术是基于信号空域特性的信号处理技术，将两者结合势必能提高卫星通信系统的抗干扰能力。本文首先深入分析两种技术的结合方式，然后在详细推导实用的盲源分离算法基础上，分别针对均匀线阵和星载相控阵天线进行仿真分析，结果表明两种技术结合可以有效提高卫星通信系统的抗干扰能力。Blind source separation is one of the signal processing techniques based on signal statistic charac- ters while nulling of orL-board phased array technique is based on space field character of the received sig- nal. Combination of the two may highly increase the anti-jamming capacity of satellite communication systems. This paper first analyzes the method for combining the two techniques. Then, under detailed derivation of the applied blind source separation algorithm, the proposed method is simulated based on uniform linear array and on-board phased array antennas. Simulation results show that the combination of the two techniques can effectively increase the anti-jamming capacity of satellite communicaiton system.
