    The optimisation of the transmission radar pulse shape to maximise either target detection or identity discrimination between the T-72 and M1 main battle tanks is investigated. Significant performance improvements in target detection and identification are obtained using such matched illumination transmission waveforms over that of standard chirped pulses View full abstract»

    In order to develop electronic protection measures (EPM) for airborne intercept radars, it is necessary to fully understand the often complex effects of different types of electronic countermeasure (ECM) techniques on the radar operation. To aid in this effort, a software-based high-fidelity simulator called SAFIRE has been developed. SAFIRE models target clutter and ECM signal returns on a pulse-... View full abstract»

    The simulation of inverse synthetic aperture radar (ISAR) imaging of moving targets is described and the effects of the target's rotations on ISAR imaging are analysed. The simulation of ISAR imaging of an aircraft with a circular motion is demonstrated. An ideal ISAR image of a target can be derived by projection of the target onto an image projection plane. Time-varying Doppler shifts induced by... View full abstract»

    Continuing the development of fast estimation methods for the design and analysis of detection algorithms, certain techniques are described for smallest of (SO) and geometric-mean (GM) constant false-alarm rate (CFAR) detectors. Methods of fast stochastic simulation are effective when applied to the class of CFAR detection algorithms, as developed and described in a set of recent papers. They do n... View full abstract»

  • Segmentation-based technique for ship detection in SAR images

    A novel segmentation-based ship detection scheme is proposed to cope with the typical features of sea clutter. In particular, it is shown that the standard 2D-CFAR schemes applied to both low- and high-resolution SAR images do not allow adequate control of the false-alarm rate for nonhomogeneity and non-Gaussianity characteristics of backscattering from the sea. The introduction of an appropriate ... View full abstract»

    The first part of the paper is a comparison between the two versions of Tough and Ward's (T/W) model (Ward and Tough 1994; and Tough and Ward 1999) in the generation of surrogate data to a compound stochastic k-distribution prescription. An overview of both versions of the model is presented together with predictor results which allow for direct comparison of the models. The second part of the pap... View full abstract»

  • Evaluation of a weather clutter simulation

    The output of a high-fidelity weather clutter simulation, designed to model a low-PRF X-, C-, or S-band phased array radar, is compared with measurements made by three radar systems. The first comparison demonstrates the simulation's ability to replicate real horizon search measurements in terms of various signal properties. The second comparison demonstrates the simulation's ability to generate s... View full abstract»

  • SAR imaging of buried objects from MoM modelled scattered field

    Publication Year: 2001 , Page(s): 167 - 172

    Synthetic aperture radar (SAR) images of resonant buried objects are modelled in the presence of ground surface clutter. The method of moments (MoM) is used to model scattered fields from a resonant buried conductor and clutter is modelled as a bivariant Gaussian distribution. A diffraction stack SAR imaging technique is applied to the ultra-wideband waveforms to give a bipolar signal image. A num... View full abstract»

  • Ground target tracking with STAP radar

    The problem of tracking ground moving targets by a moving radar (airborne, spaceborne) is addressed. Tracking of low Doppler targets within a strong clutter background is of special interest. The motion of the radar platform induces a spreading of the clutter Doppler spectrum so that low Doppler target echoes may be buried in the clutter band. Detection of such targets can be much alleviated by sp... View full abstract»

  • Investigation into the use of nonlinear predictor networks to improve the performance of maritime surveillance radar target detectors

    Previous research has claimed that sea clutter is a chaotic process with a nonlinear predictor function. Indeed, results have been reported which demonstrate that sea clutter is nonlinearly predictable, and that this predictability can be exploited, using nonlinear predictor networks, to improve the performance of maritime surveillance radars. The aim of the paper is to investigate if nonlinear pr... View full abstract»
