The performances of adaptive array algorithms are known to degrade in scenarios with moving interfering sources. Recently, several robust approaches have been proposed to overcome this problem. Below, we compare conventional and robust algorithms using shallow sea sonar data with moving co-channel interference originated from shipping noise. This data set was recorded by a towed horizontal Uniform Linear Array (ULA) ...

On the Theory of Continuous Array Processing

Aerospace and Navigational Electronics, IEEE Transactions on, 1965

The theory of continuous and discrete array signal processing is considered for tracking and navigational radar (sonar) systems. The purpose of the active array (and the associated filtering) is to detect an echo of a transmitted pulse reflected from a target in the presence of correlated reverberation or clutter and uncorrelated noise, both of which may vary from antenna-array element ...


Optimum relative speed discretisation for detection of moving objects in wide band SAR

Radar, Sonar & Navigation, IET, 2007

Here, ground moving target indication (GMTI) using synthetic aperture radar (SAR) is considered. SAR GMTI requires that relative speed between the target and the SAR platform is included in the detection algorithm. A separation between the true relative speed and the relative speed used in the SAR process will cause unfocused targets, and decrease detectability. Blind hypotheses of relative speeds ...

  • Skill Acquisition and Self-Improvement for Environmental Change Adaptation of Mobile Robot

    Learning and development are essential processes for an animat to adapt itself to environmental changes so as to accomplish a given task. This paper proposes a single mechanism for learning and self-improvement that results in learning curves similar to the "U-shape" phenomena observed in several psychological experiments concerning the human learning process such as in language acquisition. The basic idea is that (1) the animat monitors its success rate in goal achievement so as to perceive environmental changes instead of relying on signals from a teacher, and (2) in order to reuse acquired knowledge and accelerate reinforcement learning, the animat does not memorize the action values but transfers only the learned policy. The resultant policy (a state transition map where transitions indicate the best actions) may not be optimal in any given environment but it may be able to better handle differences between environments. We apply this model to a mobile robot navigation problem for which the task is to reach the target while avoiding obstacles by means of uninterpreted sonar and visual information. Our experimental results demonstrate the validity of the model.

  • 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 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.

    Recent advances in sensor technology and information processing afford a new flexibility in the design of waveforms for agile sensing. Sensors are now developed with the ability to dynamically choose their transmit or receive waveforms in order to optimize an objective cost function. This has exposed a new paradigm of significant performance improvements in active sensing: dynamic waveform adaptation to environment conditions, target structures, or information features. The manuscript provides a review of recent advances in waveform-agile sensing for target tracking applications. A dynamic waveform selection and configuration scheme is developed for two active sensors that track one or multiple mobile targets. A detailed description of two sequential Monte Carlo algorithms for agile tracking are presented, together with relevant Matlab code and simulation studies, to demonstrate the benefits of dynamic waveform adaptation. The work will be of interest not only to practitioners of rada and sonar, but also other applications where waveforms can be dynamically designed, such as communications and biosensing.
