Mode composition beamforming(MCB)is a frequency-domain rotating beamforming method for rotating acoustic source localization.Compared with other rotating beamforming methods,MCB has both wide applicability and high computational efficiency.The expression forMCB in literature is however not suitable for the application of deconvolution algorithms,which limits further improvements of dynamic range and spatial resolution ofMCB.In this work,application of deconvolution algorithms to MCB is investigated.Firstly,the expression of MCB is transformed into a matrix form.Then the deconvolution algorithms of MCB,including DAMAS and CLEAN-SC,are derived based on the matrix form of MCB.Nextly the deconvolution algorithms of MCB are verified through a benchmark simulation case.Lastly deconvolution algorithms of MCB are applied in a phased array measurement for the rotor of an unmanned aerial vehicle to improve the dynamic range and spatial resolution of rotating source localization. 展开更多
