Data Sensitivity Analysis of Fast Time-domain Analytical MVDR Algorithm

Published: 17 May 2021 Publication History

Abstract

Data sensitivity is a key problem in the application of adaptive beamforming technology. Based on the analysis of the principle of fast time-domain analytical MVDR algorithm, the influence of the amplitude fluctuation of array signal on fast time-domain analytical MVDR beamforming algorithm is analyzed by using numerical simulation and sea test data. The results show that the amplitude fluctuation has little influence on the conventional beamforming algorithm, but has great influence on the fast time domain analytical MVDR algorithm, so the fast time domain analytical MVDR beamforming algorithm requires high channel consistency of each hydrophone.
