    High range resolution (HRR) moving target indicator radar is becoming increasingly important for many military and civilian applications involving the detection and classification of moving targets within a clutter background. For ground-based HRR radar, when targets are moving slowly or near-broadside and the coherent processing interval or dwell time is not too long, the effects of range migrati... View full abstract»

    Simulation and performance estimation methodologies are developed for constant false-alarm rate (CFAR) detection algorithms based on the powerful concept of importance sampling (IS). Such algorithms involve crossings of a random threshold. Compression of the threshold density function produces the required biasing to implement IS procedures. Adaptive optimisation of simulation estimators and estim... View full abstract»

    The single point statistics of some high-resolution low-grazing angle radar sea clutter are examined. Three different distributions are used to model the cumulative density of the data. The Weibull and the K-distribution both require the addition of a Rayleigh distributed component to give a good fit to the data. This Rayleigh distributed component has a mean level significantly higher than the th... View full abstract»

    Many blind beamforming algorithms, such as constrained cyclic adaptive beamforming (C-CAB), use cyclostationarity to estimate the steering vector and adaptively obtain the linearly constrained minimum variance (LCMV) optimum solution. However, LCMV methods are sensitive to the mismatch caused by the uncalibration array or estimate error. After discussion of this mismatch, a robust blind beamformin... View full abstract»

    Synthetic aperture radar (SAR) clutter may be characterised by its single-point statistics and its correlation structure, both of which should be exploited in applications such as target detection. The non-Gaussian distributions associated with SAR clutter can be incorporated in detection schemes based on single-point statistics in a reasonably straightforward manner. However, use of the correlati... View full abstract»

    The authors describe a focusing procedure, for use in step-frequency ISAR imaging, which corrects for the assumption of a rectangular data sampling grid; searches for focused images can be shortened using a two stage procedure. The first stage of processing constructs an intermediate image from which slant range blurring is removed, The second stage removes the slant range dependent, cross range b... View full abstract»
