With the development of modern automobile technology, automobile structure has become more and more complex, and the requirements for control technology of automobile noise source have become higher and higher. Traditional sound source control technology has been difficult to meet the modern needs. A uniform circular array signal model was constructed, and the corresponding array parameters were defined, including the calculation method of array spacing, array directivity and main lobe width. Finally, the MATLAB software was used, and the characteristics of the circular array pattern were studied. And the influence of the element spacing and the number of array elements on the array pattern was analyzed. The results show that the uniform circular array can obtain better resolution, and is more practical.
