Abstract：When there are multiple coherent sources in the space, the current approaches which measure the pressure by the use of a single measurement plane can’t effectively identify the specific source. In order to solve the problem, the method of rotating the measurement surface is put forward, making the distance between coherent sources and the measurement plane is unequal. The measurement is carried at two sides of the coherent sources. Based on the propagation theory and the method of two-dimensional Fourier transform, the specific source between the sources can be separated. Numerical simulation is performed through two groups of coherent sources at different frequency and different distances, and the result verifies the correctness and effectiveness of the proposed method.
