Striation-based beamforming for estimating the waveguide invariant with passive sonar.
The waveguide invariant summarizes the pattern of constructive and destructive interference between acoustic modes propagating in the ocean waveguide. For many sonar signal-processing schemes, it is essential to know the correct numerical value for the waveguide invariant. While conventional beamforming can estimate the ratio between the waveguide invariant and the range to the source, it canno...
متن کاملParallel Subspace Projection Beamforming for Autonomous, Passive Sonar Signal Processing
Adaptive techniques can be applied to improve performance of a beamformer in a cluttered environment. The sequential implementation of an adaptive beamformer, for many sensors and over a wide band of frequencies, presents a serious computational challenge. By coupling each transducer node with a microprocessor, in-situ parallel processing applied to an adaptive beamformer on a distributed syste...
متن کاملRobust Krylov-Subspace Methods for Passive Sonar Adaptive Beamforming
Krylov-subspace methods, such as the multistage Wiener filter and conjugate gradient method, are often used for reduced-dimension adaptive beamforming. These techniques do not, however, allow for steering vector mismatch, which is typically present in many applications of interest, including passive sonar. Here, we discuss recently proposed robust methods that do allow for steering vector misma...
متن کاملLow-Complexity Uncertainty Set Based Robust Adaptive Beamforming for Passive Sonar
Recent work has highlighted the potential benefits of exploiting ellipsoidal uncertainty set based robust Capon beamformer (RCB) techniques in passive sonar. Regrettably, the computational complexity of forming RCB weights is cubic in the number of adaptive degrees of freedom, which is often prohibitive in practice. For this reason, several low-complexity techniques for computing RCB weights, o...
متن کاملBeamforming for Active Sonar Imaging
This thesis addresses the use of adaptive beamforming and imaging methods applied to active sonar. While adaptive beamformers are known to offer improved performance when applied to passive sonars, their use is limited in active sonar systems. In this thesis, we investigate the potential performance gains of using adaptive beamforming methods for a range of active sonar applications. Key challe...
