Frequency wavenumber power spectrum
Modified Spatial Autocorrelation method (MSPAC)
The Modified Spatial Autocorrelation (MSPAC) was introduced by Bettig et al. (2001) [6] after pioneer paper of Aki (1957)[7]. This method allows computing spatial autocorrelation coefficients for any arbitary array configurations.

The co-array is defined as the set of all possible combinations of two array sensors (Haubrich, 1968 [8]): the array can thus be divided into several semicircular sub-arrays (hereafter called rings) as described in Bettig et al. (2001) [6]. Since, for each ring, an azimuthal and radial integration is performed when computing spatial autocorrelation values, the design of rings results from a compromise between a number of sensors pair per ring as large as possible and a ring thickness as small as possible.
