This letter proposes a localization method for mixed far-field (FF) and near-field (NF) sources based on second-order statistics (SOS) with generalized symmetric sparse linear arrays. First, the DOAs ...

Comprehensive design considerations for 2D matrix arrays KLM and FEM (PZFLEX) models were used to compare piezoelectric materials in 2D matrix transducer designs, including PZT5H, high dielectric ...
