| 英文摘要: |
| It is required in the diagonally loaded robust adaptive beamforming the automatic determination of the loading level which is practically a challenging problem. A constant modulus restoral method is herein presented to choose the diagonal loading level adaptively for the extraction of a desired signal with constant modulus (a common feature of the phase modulation signals). By introducing the temporal smoothing technique, the proposed constant modulus restoral diagonally loaded robust adaptive beamformer provides increased capability compared with some existing robust adaptive beamformers in rejecting interferences and noise while protecting the signal-of-interest. Simulation results are included to illustrate the performance of the proposed beamformer. |
