摘　　要：文中研究了一种基于信号到达方向 (DOA)估计的卫星多波束天线自适应调零方案 ,计算机仿真结果表明 ,此方案可以实现对卫星天线覆盖区内的干扰信号进行高分辨强抑制 。This paper is to assess the perfomance of an adaptive nulling scheme based on direction of arrival estimation when used with multiple beam antennas on communication satellites. The results of theoretical study and computer simulation show that the scheme can offer the advantages of higher resolution, stronger suppression and better SINR performance over the SMI method. Moreover, this method can be free from the requirement of reference signal in traditional adaptive nulling system.
