Calculation of Array Gain in the Reverberation Field

Abstract:

If the number and the location of each cell in the array is determined, the space array processing gain is constant in designing the uniform line array in isotropic acoustic field. However, the spatial distribution of reverberation field will affect against the array gain, when the arrays are in anisotropic reverberation field. Reverberation is the unique interference of active sonar, and the energy distribution of space in reverberation field is anisotropic and random. Therefore, the arrays gain problem can be get in researching on the correlation between arrays in the reverberant field. In this paper, the calculation method is simple and useful which is calculated line array gain using the correlation coefficient in the reverberant field.
