摘要
单通道接收阵列测向系统设备量少,造价低,因而引起了人们的研究兴趣。当阵元切换控制信号存在延时时,导向矢量发生改变,从而导致系统测向误差的增加,甚至错误。对延时加以校正后,能够进行高精度测向。仿真实验的结果表明了理论分析的正确性。
Mono-channel direction finding system attracts one＇s interest because of its simple hardware and low cost. When the controlling signal for antenna has a time delay, the steering vector is changed, so the accuracy deteriorates, even mistakes. After the time delay is revised, high accurate DOA could be got. The results of experiments prove the rightness of theoretical analysis.
