Abstract
The response of the optimal beamformer, whose output power is (CTR-1C)-1 where R is the data covariance matrix and C a steering vector, is examined for the case that a single source produces an angular power density spectrum of the all-pole type. Such a spectrum may be an approximation to the actual power spectrum of of a source received in shallow water where random surface scattering spreads the source rays. It is shown that the all-pole matrix R is explicitly invertible and simple expressions can be obtained for the angular response of the optimal beamformer.
