英文摘要：

To solve the problem of efficient generation and structural creation basis of acoustic array during the measurement of multi-source movement sound field, a coaxial circular array based on irregular grids is chosen as a fundamental structure. The detailed segment scheme of irregular grids is formed. An array mathematical matrix model is established using a uniform probability density thought partition multiple the same zoning area of array surface and layout the same number grid points in each zone. The number of rows and columns of model is the same as the number of partitions and grid points in each partition respectively. Based on this model and the deduced random array structural filter condition for the measurement of multi-source movement sound field, the candidate array is created from the array matrix model by a pseudo-random generation method. Furthermore, the objective evaluating indicator and principle are given, and the target array is generated from the candidate array according to this principle. By simulation and real vehicle experiments demonstrate the effectiveness of generating process and the build robust of array performance. The method translates the complex and tedious process of the generation of random array structure into an array microphone positions＇ matrixes optimization operation, which greatly improve the speed of array structural generation. At the same time, it gives random sparse acoustic array structural creation principle for the measurement of the multi-moving sound sources.
