Parallel 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 کاملFPGA signal processing for radar / sonar applications
R and sonar applications are signalprocessing intensive and heavily rely on the efficient implementation of such digital signal-processing (DSP) algorithms as filtering, transforms and modulation. In past systems, conventional digital signal processors were used to perform many of these algorithms. However, field-programmable gate arrays (FPGAs) deliver an order of magnitude higher performance ...
متن کاملTheory and Implementation of Advanced Signal Processing for Active and Passive Sonar Systems
Progress in the implementation of state-of-the-art signal processing schemes in sonar systems has been limited mainly by the moderate advancements made in sonar computing architectures and the lack of operational evaluation of the advanced processing schemes. Until recently, sonar computing architectures allowed only fast-Fourier-transform (FFT), vector-based processing schemes because of their...
متن کاملMatched Field Processing for Active and Passive Sonar
The complexity and dynamics of shallow water limit the performance of adaptive array processors. Matched field processors are especially sensitive since they require accurate environmental models to construct signal replica vectors. The long term goals are i) to determine processors performance limits and ii) to develop robust algorithms for adaptive array processing in shallow water for both a...
متن کاملSonar Signal Processing using Tangent Clusters
Robert Mandelbaum Max Mintz General Robotics and Active Sensory Perception (GRASP) Laboratory Department of Computer and Information Science University of Pennsylvania Philadelphia, PA 19104 Abstract We describe a novel approach to the extraction of geometric features from sonic data. As is well known, a single sonar measurement using a standard PolaroidTM sensor, though yielding relatively acc...
