    Techniques from two seemingly unrelated areas, X-ray transmission tomography and ground wave propagation attenuation (at much lower frequencies), are combined to produce a technique for imaging the dielectric properties of an inhomogeneous surface. A small-scale imaging experiment at microwave frequencies is described, demonstrating the potential for the technique View full abstract»

    The authors present a decoupling joint probabilistic data association (DJPDA) algorithm by decoupling the JPDA algorithm into separate PDA algorithms. To demonstrate the decoupling idea, they derive a set of complete decoupling PDA equations for two and three targets. Since these equations are impractical for real-time systems and are unavailable for an arbitrary number of targets, an approximate ... View full abstract»

  • Adaptive time delay and Doppler shift estimation for narrowband signals

    Publication Year: 1999, Page(s):243 - 250

    A computationally inexpensive algorithm suitable for fast, high-resolution estimation of time delays and Doppler shifts (which are necessary for target ranging and tracking) between narrowband signals is presented. The algorithm uses a modulated Lagrange interpolation filter and an LMS-type algorithm. The problem of delay and Doppler estimation is reduced to a linear regression problem. Convergenc...

    The authors introduce a multidisciplinary perspective on adaptive sensor array processing. The uses of adaptive sensor array processing for the applications of radar detection using space-time adaptive processing, partially adaptive radar detection, multispectral infra-red imaging, optical moving target detection and synthetic aperture radar automatic target detection and recognition are presented View full abstract»

    The statistical mechanism ruling the reverberation from the seabed in high-resolution sonar devices is investigated. The signal received from a sonar cell is assumed to arise from the coherent sum of a random number of independent elementary contributions. Under proper conditions regarding the surface roughness and the incidence angle, the observables can be modelled as compound-Gaussian random va... View full abstract»

  • Efficient computation of the eigensubspace for array signal processing

    The authors present an efficient technique for computing the eigensubspace spanned by a received array data vector. First, the sensor array is partitioned into several subarrays without overlapped sensors. The basis matrix for the signal subspace of each subarray is computed. Using these basis matrices, an additional subarray is constructed and the basis matrix for the corresponding signal subspac... View full abstract»
