[0033] specific implementation plan
[0034] The present invention will be further described below through specific implementation examples.
[0035] In this implementation example, the spoke array is selected as the measurement array to figure 1 60 microphones are arranged in an irregular manner as shown, the spacing between the microphones is not equal, and the working frequency band is 0.5-8kHz.
[0036] Suppose the sound source is a point sound source, located at (-0.5m, 0.5m, 0.8m), the background noise is not considered for the time being, the sound source frequency is 4kHz, and the sound source intensity is 1Pa. The search area of interest is a cuboid, whose center is located at the coordinate origin O, the X and Y axes are searched from -2m to 2m, the Z axis is searched from 0m to 3m, and the search step is 0.02m. The planar array is located in the x, y coordinate plane, and the center of the array surface is located at the coordinate origin.
