| 摘 要： | 阵列通道幅相不一致性严重影响测向性能。基于辅助源的相关校正理论,研究了通过在天线馈电口输入辅助信号,再对信号求相关来实现对阵列通道不一致性的校正;并分析了基于多基线数字干涉仪体制的测向原理,利用五元圆形天线阵列估计出了地面目标的到达角。此外,还讨论了所有算法的DSP实现,计算机模拟证实了方法的有效性。

| Abstract: | The performance of direction-of-arrival (DOA) estimation algorithms is seriously degenerated when there are errors in array manifold. A correlative based technique, which estimates and calibrates the circle array antenna channel uncertainty used an auxiliary source, is given in this paper. Moreover, the high-accuracy DOA estimation algorithm using digital interferometer and all these algorithms DSP implementations are also studied. The efficiency of the method is confirmed by computer simulation. |
