    The feasibility of a modified gain extended Kalman filter using bearings-only measurements is explored for underwater applications. A much simpler version of the modified function is considered for the development of this algorithm. This algorithm estimates target motion parameters and detects target manoeuvres, using zero mean chi-square distributed random sequence residuals, in a sliding window ... View full abstract»

    The use of a non-co-operative television transmitter as the illuminator for a bistatic radar system is investigated. A signal processing scheme is developed that allows airborne targets to be detected and tracked using only the vision or sound carrier of the television broadcast. This scheme requires no synchronisation with the television transmitter, and uses the Doppler shift and bearing of targ... View full abstract»

    It is shown that the azimuth radiation pattern direction of a multi-probe dielectric resonator antenna (DRA) can be changed by exciting different probes within the dielectric when the other probes are open-circuited. When two probes are excited simultaneously, smaller steering increments can be obtained without significantly changing the beamwidths. In some combinations, a pair of probes has a sig...

    Subspace or projection methods, such as MUSIC, have been shown to perform excellently when used for angle-of-arrival estimation, especially in the case of small sample size. The drawback of those methods is their heavy computational load when used for arrays with a large number of elements. The paper investigates the performance of a fast subspace-estimation method which has been proposed for the ... View full abstract»

    The authors present a thorough performance analysis of two covariance matrix estimators, the sample covariance matrix estimator (SCME) and the normalised SCME (NSCME), which are employed by adaptive radar detectors in Gaussian and compound-Gaussian clutter. Theoretical performance predictions are derived, compared with the modified Cramer-Rao lower bound and checked with real-life sea clutter data... View full abstract»

  • Wide-swath space-borne SAR using a quad-element array

    The authors describe an array-based approach to increasing the swath width of space-borne synthetic aperture radar beyond the limit normally imposed by ambiguity. The nulls of a quad-element rectangular array are used to suppress returns from range and azimuth ambiguities, allowing the swath to be increased by a factor of approximately four. A conceptual design is presented, based on ERS-1, that g... View full abstract»

  • One-dimensional scattering centre extraction for efficient radar target classification

    A technique is presented to extract one-dimensional scattering centres of a complex radar target. To maintain super-resolvability, estimation accuracy and robust detection of scattering centres, the model-based technique, and the FFT-based technique, are combined in an efficient manner to take advantages of both techniques. The performance of the proposed algorithm is examined through Monte-Carlo ... View full abstract»
