In order to improve the directional accuracy of 3D rotation acoustic array , the static experimental research is carried out. First, the state equation and observation equation are established in colored noise environment, and the dynamic model of moving acoustic array is also obtained. The loop simulation test device is designed based on a group comprising microphone, amplifier conditioning, data acquisition card, adjustable acoustic array configuration device, the filter circuit, data acquisition card, A / D converter and recorder modules. Finally, the directional static experimental is carried out, and the experimental data is analyzed based on triangular orientation theory, it is laid the theoretical foundation for further study dynamic experimental.
