  • OFDM Modem Development

    This chapter describes the modem implementation aspect and presents some example designs of orthogonal frequency‐division multiplexing (OFDM) based acoustic modems. To have a standalone underwater acoustic modem, which supports point to point communications, the following components are needed: hardware platform consisting of various units and DSP firmware. Demonstration of acoustic communication algorithms can be accomplished with low cost in the air, which often serves the educational purposes. The underwater sensor network (UWSN) lab at University of Connecticut has developed an OFDM lab modem prototype based on a DSP development board, as discussed in the chapter. AquaSeNT, a startup from the University of Connecticut, has licensed the OFDM modem technologies from the University of Connecticut and has launched a commercial modem product, which is also discussed in the chapter.

  • From Bat Pinnae to Sonar Antennae: Augmented Obliquely Truncated Horns as a Novel Parametric Shape Model

    Biosonar systems operating in air (bats) use intricate baffle shapes for shaping the sonar beam pattern. Because of its relative ease of implementation, beamforming with such baffle shapes is also an attractive solution for enhancing the sonar-sensing capabilities of animats. The work presented here introduces a novel family of parametric, biologically inspired, baffle-shapes for sonar sensors: augmented obliquely truncated horns. The structural features of these shapes are: an obliquely truncated horn, a washboard ripple pattern on its inner surface, and a pin-shaped flap ("tragus") partially occluding the aperture through which sound enters the baffle. Shapes generated by this model can be completely controlled with 22 parameters. Numerical methods to generate representations of these shapes, evaluate their acoustic properties, and visualize the results are described. The investigated acoustical system properties are: directivity pattern, shape of iso-gain surfaces in three dimensions and gain contours on planar cuts through the spatial distribution of the gain. The last property (cuts) serves as a representation of the shape of a sonar spotlight shone onto an extended target of relatively low curvature. The results demonstrate that ripple and tragus have a profound impact on the functional properties of the baffle shapes. The most prominent effects include breaking of symmetry and generation of side lobes in different frequency bands. The two features have been shown offer the opportunity to shape the spatial distribution of receiver gain into a large number of profoundly different configurations. Evidence of interactions between the features indicates that a combination of both features may generate system properties inaccessible through any one feature alone. The tool-chain of numerical methods used in the present work establishes a foundation for f uture investigations of performance measures to be used in optimizing the baffle shapes for a particular task.

  • Spectral Analysis of Signals:The Missing Data Case

    Spectral estimation is important in many fields including astronomy, meteorology, seismology, communications, economics, speech analysis, medical imaging, radar, sonar, and underwater acoustics. Most existing spectral estimation algorithms are devised for uniformly sampled complete-data sequences. However, the spectral estimation for data sequences with missing samples is also important in many applications ranging from astronomical time series analysis to synthetic aperture radar imaging with angular diversity. For spectral estimation in the missing-data case, the challenge is how to extend the existing spectral estimation techniques to deal with these missing- data samples. Recently, nonparametric adaptive filtering based techniques have been developed successfully for various missing-data problems. Collectively, these algorithms provide a comprehensive toolset for the missing-data problem based exclusively on the nonparametric adaptive filter-bank approaches, which are robust and ac urate, and can provide high resolution and low sidelobes. In this book, we present these algorithms for both one-dimensional and two- dimensional spectral estimation problems.

  • OFDM Receiver with Parameterized External Interference Cancellation

    Underwater acoustic communication channels are prone to external interference from various sources, such as the interference from marine animals, human activities and sonar operations. This chapter focuses on explicit mitigation of an external interference with a certain time duration and bandwidth. With the parameterized interference model, an iterative orthogonal frequency‐division multiplexing (OFDM) receiver with interference cancellation is designed to perform data processing and interference estimation/cancellation iteratively. The chapter talks about the parameterization method that represents an external interference via a number of parameters. It presents an OFDM receiver, where OFDM receiver decoding is performed with interference estimation and cancellation iteratively. The chapter contains simulation and experimental (Atlantic Undersea Test and Evaluation Center (AUTEC)10 and SPACE08) results, that validate the performance of the iterative receiver.

  • Matrix CRLB Scaling Due to Measurements of Uncertain Origin

    In many estimation situations, measurements are of uncertain origin. This is best exemplified by the target-tracking situation in which at each scan (of a radar, sonar, or electro-optical sensor), a number of measurements are obtained, and it is not known which, if any, of these is target originated. The source of extraneous measurements can be false alarms-especially in low- SNR situations that force the detector at the end of the signal processing chain to operate with a reduced threshold-or spurious targets. In several earlier papers, the surprising observation was made that the Cram¿¿r-Rao lower bound (CRLB) for the estimation of a fixed parameter vector (e.g., initial position and velocity) that characterizes the target motion, for the special case of multidimensional measurements in the presence of additive white Gaussian noise, is simply a multiple of that for the case with no uncertainty. That is, there is a scalar information-reduction factor; this is particularly useful as it allows comparison in terms of a scalar. In this paper, we explore this result to determine how wide the class of such problems is. It turns out to include many non-Gaussian situations. Simulations corroborate the analysis.

  • Biomimetic Sonar Processing: From Dolphin Echolocation to Artificial Neural Networks

    Analysis of animal performance can provide important cues about the design of automated artificial biomimetic systems. On the basis of behavioral observations, we have been developing models of dolphin echolocation ability that have applicability to the design of biomimetic sonar systems. A dolphin was trained to perform an echolocation delayed matching-to-sample task. The clicks the animal generated during task performance were recorded and digitized along with the echoes returned by the stimulus objects. The dolphin's performance was then modeled using artifical neural networks.
