Sonar array processing borrows from geophysics

IEEE Spectrum, 1989

A modification of a simple hybrid signal-processing technique introduced in 1973 by Tad Ulrych, a geophysicist, and his colleagues is described. The method can improve the performance of one-dimensional, equispaced sensor arrays under certain conditions, so that they perform as well as arrays that are up to two or three times longer under high signal-to-noise ratio conditions. Combining approaches used ...


Sparse sample matrix inversion with diagonal loading for reverberation suppression

2011 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2011

The main problem of active sonar detection is that the reverberation has spatial and temporal two-dimensional coupling characteristic which is similar to clutters in airborne radar. This paper presents a sparse sample matrix inversion with diagonal loading (SSMI-DL) for reverberation suppression in active sonar. The proposed method transfers Pulse Doppler radar STAP processing techniques into active sonar application, which utilizes ...

The chip, when coupled with a sonar bearing and range estimation unit, receives an image of the environment as a voltage waveform. The bearing of an object is given by the magnitude of the signal, while its range is given by its ...

  • Sonar array processing borrows from geophysics

    A modification of a simple hybrid signal-processing technique introduced in 1973 by Tad Ulrych, a geophysicist, and his colleagues is described. The method can improve the performance of one-dimensional, equispaced sensor arrays under certain conditions, so that they perform as well as arrays that are up to two or three times longer under high signal-to-noise ratio conditions. Combining approaches used in traditional Fourier analysis (which gives good results only for weak signals) and high-resolution signal processing (which resolves only strong signals well), the technique yields enhanced resolution for both. The application of the hybrid technique to sonar processing is described.<<ETX>>

  • Sparse sample matrix inversion with diagonal loading for reverberation suppression

    The main problem of active sonar detection is that the reverberation has spatial and temporal two-dimensional coupling characteristic which is similar to clutters in airborne radar. This paper presents a sparse sample matrix inversion with diagonal loading (SSMI-DL) for reverberation suppression in active sonar. The proposed method transfers Pulse Doppler radar STAP processing techniques into active sonar application, which utilizes the inverse reverberation covariance matrix to obtain adaptive weights and avoids singular reverberation covariance matrix with diagonal loading due to limited available received data. Simulation results are provided to verify that the SSMI-DL is more effective for improving slowly moving target detection for CW pulse than the conventional methods.

  • A time-series processor for sonar mapping and novelty detection

    A time-series processor chip, intended for sonar mapping and novelty detection applications, has been designed, fabricated and tested. The chip, when coupled with a sonar bearing and range estimation unit, receives an image of the environment as a voltage waveform. The bearing of an object is given by the magnitude of the signal, while its range is given by its time following the transmission of the sonar 'ping'. The chip stores this voltage waveform in a bank of sample-and-hold (S/H) elements and compares it to a previously stored trace. Objects that move in either azimuth or range are immediately detected and reported. The chip contains 54 S/H elements that are triggered by an on- board timer. The change detector can detect motion in bearing and range of 10 degrees/s and 11 cm/s, respectively. The maximum range is approximately 5 m. Operating in the CMOS subthreshold region of operation, the novelty detection chip is designed for ultra-low power and micro-footprint smart surveillance systems. Implemented in a CMOS 0.5 um process, it consumes less than 20 uW @ 8 Hz repetition rate (and less than 6 uW quiescent) with a 3 V supply and occupies less than 0.3 sq. mm.

  • POS/SV-an aided inertial navigation system for submersible vehicles

    Describes a position and orientation system for submersible vehicles (POS/SV), designed to provide a full navigation solution for submersible vehicles (SV). Its intended applications are those requiring accurate and continuous position and orientation data in very deep or very shallow water where acoustic positioning systems (APS) alone become sporadic, noisy and generally unreliable. These applications include positioning for SV navigation, positioning and orientation for template survey, deep water multibeam sonar bathymetry requiring both position and orientation for sonar motion compensation and data georeferencing, site surveying and pipe and cable surveying and synthetic aperture sonar (SAS) motion compensation.

  • Two approaches for the estimation of time-varying amplitude multichirp signals

    This paper addresses the problem of time-varying amplitude multichirp signals parameter estimation. We compare two approaches which require a model for the amplitude. First, we use a basis of time-localized functions associated with Bayesian estimation. Secondly, we use an autoregressive model associated with a mixed high-order ambiguity function/Kalman filter estimation. Results show that both methods are efficient to solve this estimation problem.

  • Applications and results at sea of adaptive array processing in passive sonar

    Adaptive array processing has been extensively studied during several decades for underwater acoustic applications. But up to now, very few applications have been developed, or, at least, appear in the literature. This is due to the relatively great amount of calculation needed by adaptive processing compared to conventional beamforming, and perhaps, by the relatively disappointing results obtained in the first applications (mainly towed array in deep water) when considering the needed extra processing load. The results obtained in recent applications demonstrate the great interest of adaptive beamforming.

  • Sonar signal classification using the BCM learning algorithm

    Previous work by the author has demonstrated the capability of the Bienenstock Cooper Munro (BCM) model (proposed in 1982) of neural synaptic modification to perform feature extraction, thus enhancing the performance of automated classifiers. Recent work has applied the BCM algorithm to sonar images of minelike objects, with the output of the BCM networks fed into a neural network classifier. This paper demonstrates the capability of this approach to classify, objects as minelike or non-minelike, and to further classify the minelike objects by type.

  • New archaeological uses of autonomous underwater vehicles

    This paper explores the intersection of two fields of research: autonomous underwater vehicles (AUVs), and archaeology in the deep sea. Archaeology in the deep sea poses a range of difficult, interesting problems for autonomous underwater vehicles. These include broad area sonar searches, target identification, and precision survey. Broad area sonar searches for archaeology have requirements similar to those in other AUV applications collecting sonar data to locate targets for further inspection. The authors briefly discuss what existing vehicles can contribute to archaeological searches. They then describe the challenges for AUVs in identifying archaeological sites. Then, they discuss the importance of precision survey of archaeological sites and its implications for vehicle design and control. By "mowing the lawn" with computer-controlled tracklines over an archaeological site, an AUV could collect imagery and sonar data for precise maps of a particular site. We propose an archaeology-speciflc AUV to conduct such surveys and describe the requirements for such a vehicle to work in precision, instrumented environments.
