                 Abstract: In order to make the underwater test acoustic array have strong anti-interference ability, the array
                 is often required to have a low side lobe. In this paper, a design method of spiral space array is proposed,
                 which can greatly reduce the sidelobe height of volume array and improve the bearing estimation ability of
                 underwater targets by taking advantage of the sparse spatial distribution characteristics of spiral structure. In
                 this paper, the construction method and element coordinate parameters of the spiral space array are given,
                 and the directivity, bearing estimation ability and array gain are compared with the conventional volume array
                 such as the cylindrical array and the biconical array. The simulation results show that the directional sidelobe
                 of the spiral space array is the lowest and the most flat in the horizontal direction, and the false peak height is
                 the lowest when estimating the target’s bearing, and the bearing estimation ability of the target is significantly
                 improved compared with the biconical array and the cylindrical array.
