Abstract	The capability to reject strong and spatially spread interferences by means of subarray adaptive beamforming in presence of sensor dispersions is analyzed. Subarray adaptive beamforming is a beamspace adaptive beamforming well suited for rapid convergence applications, and in which the degrees of freedoms are automatically allocated to the suppression of the strongest eigenvalues. The statistics of the array gain in presence of spatially spread jammers are derived and applied to the purpose of reverberation suppression in active sonar in Continuous Wave mode. Examples on real data are provided to support the theoretical results.
