摘要 为了满足宽带侦收的要求,提出了一种新的基于环形阵列的宽带天线阵列配置方案,利用2组独立空间欠采样通道得到有模糊的信号空域信息,并结合一定的解模糊算法和配对方法得到无模糊的空间信号到达角(DOA)估计.仿真结果表明,所提算法在搜索量小的优势下能实现二维方向角的高精度估计及正确配对,且2组通道的采样数据可并行处理,增强了算法的实时性. A new method of array geometry arrangement based on ring array for wideband reconnaissance receiver is proposed. With the aid of aliased spatial information from two independent sampling channels, solving ambiguity algorithm and pair method, it can provide unambiguous direction of arrival （DOA） estimation. The simulation result indicates that azimuth angle and elevation angle are estimated in high per-formance and paired correctly under the circumstance of small search load. Data obtained from two channels can be processed separately. Real-time performance of algorithm is improved.
