【摘要】In order to reduce the computational complexity of correlative interferometer direction finding (DF) ,this paper presents a fast DF algorithm based on multi-resolution correlation process-ing .Unlike the traditional correlative interferometer that calculates the correlation coefficients in the entire range of angle ,the proposed fast algorithm uses the mode of stepwise measurement . Firstly ,the direction of wave arrival is measured roughly ,then the rough measurement results are taken as guidance ,fine measurement is performed in a smaller range ,w hich shortens the running time dramatically .At the same time ,the fast algorithm does not cause any loss of precision .The op-timal scale between samples for rough measurement and samples for fine measurement is deduced . Theoretical analysis and computer simulation results confirm that the proposed fast algorithm can shorten the computation time remarkably ,the proposed algorithm has practical application value in instantaneous DF .%为降低相关干涉仪测向的计算复杂度，提出了一种基于多分辨率相关处理的快速测向算法，与在全角度范围计算相关系数的传统相关干涉仪不同，快速算法采用逐级测量的方式，先粗测来波方向，用粗测的结果做指引，在较小的角度范围内进行精细测量，从而显著减
