Simulation Research of the Influence of Random Phase Disturbance on MVDR Beam Former

Abstract:

In practical sonar engineering, the random phase disturbance error will be existed in the output signals of every channels of hydrophone because of the complexity of ocean diffuse environment and the disturbed beam. So only the statistical methods can be used to analyze these errors. By this way, the influence of the different output signals of every channels of hydrophone on MVDR Beam former and the array gain is researched, and also the computer simulation is completed.
