Equivalent source method near-field acoustical holography method based on sparse Bayesian focusing

The invention discloses an equivalent source method near-field acoustical holography method based on sparse Bayesian focusing. The method comprises the following steps: arranging M microphones in a sound source near-field radiation area so as to measure and obtain holographic surface sound pressure...
