摘要: 以自适应阵列的输出信干噪比(SINR)为对象,研究了通道幅相不一致性对它的影响.理论分析结果表明,幅相不一致性主要对期望信号的增益有一定的降低,但不影响对干扰的抑制,由此所造成的SINR损失很小.仿真结果证明了理论分析的正确性.

关键词: 自适应阵列, 信干噪比, 幅相误差

Abstract: This paper analyzes the output SINR of adaptive array antenna in the presence of amplitude and phase errors. The analysis shows that the amplitude and phase errors has little effect on the output SINR of adaptive array antenna. The results were validated by computer simulation.

Key words: amplitude and phase errors, adaptive antenna array, SINR
