英文摘要Compressive sensing (CS) is a newly emerging method in information technology that could reduce sampling efforts extensively by conducting L1 optimization. In this work, CS is extended to array beamforming applications and two algorithms (CSB-I and CSB-II) are presented with the assumption of spatially sparse and incoherent sound sources. The coherence of measurement matrix are examined separately and compared, and these two algorithms are also examined using both simulation and aeroacoustic experiments. The simulation case clearly shows that the CSB-I algorithm is quite sensitive to the sensing noise. The CSB-II algorithm, on the other hand, is more robust to noisy measurements. In addition, aeroacoustic tests of an airplane model demonstrate the good performance in terms of resolution and sidelobe rejection of CSB-II algorithm.; EI; 0
