摘要
相对线阵干涉仪,二维圆形阵列干涉仪具有测向精度均匀、易于共形设计等优点。针对均匀圆阵,提出了一种基于信号分区和相关运算的测向算法,进行了仿真分析。结果表明在宽频带范围内该算法能够正确解模糊,具有较高的测向精度。
Relative to linear array interferometer,two-dimensional circular array interferometer has the advantages such as uniform direction-finding accuracy,easy conformal design and so on.Aiming at uniform circular array,this paper puts forward a direction-finding algorithm based on signal partition and relative operation,performs the simulation analysis.Results show that the algorithm can solve ambiguity correctly within the wide-band range,has superior direction-finding accuracy.
