  • The Signal and Interference Environment in Passive Bistatic Radar

    Publication Year: 2007, Page(s):1 - 10
    Cited by:  Papers (21)  |  Patents (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1807 KB) | HTML iconHTML

    We present a review of the properties of some signals that may be used as illuminators of opportunity in passive bistatic radar systems. It is shown that such signals are not ideal for radar purposes, though modern digital modulation formats are to be preferred, since their ambiguity performance is better and in general does not vary with time. However, with any type of signal the ambiguity perfor... View full abstract»

  • Event Location from Noisy Time-of-Arrival Data by Total Least Squares

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (276 KB) | HTML iconHTML

    While it is widely known how to reduce the time-of-arrival equations to a linear system, this appears to be of limited value for noisy, over-determined problems as there is no guarantee that the standard least squares solution of this linear system will be close to the maximum likelihood solution of the errors in the original problem. This paper uses the idea of errors-in-variables to construct a ... View full abstract»

  • Robust Guaranteed Cost State Estimation for Nonlinear Stochastic Uncertain Systems Via an IQC Approach

    Publication Year: 2007, Page(s):17 - 22
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB) | HTML iconHTML

    This paper presents a new approach to robust nonlinear state estimation based on the use of integral quadratic constraints and minimax LQG control. The approach involves a class of state estimators which include copies on the system nonlinearities in the state estimator. The nonlinearities being considered are those which satisfy a certain global Lipschitz condition. The linear part of the state e... View full abstract»

  • Netted Radar Theory and Experiments

    Publication Year: 2007, Page(s):23 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (934 KB) | HTML iconHTML

    In this paper, the performance netted radar is evaluated in terms of the ambiguity function. A three dimensional netted radar ambiguity model has been formulated. A software tool has been developed to assess the netted radar ambiguity and resolution properties. Simulation results show that the degradation of range and Doppler resolution are strongly dependent on system and target geometry. We then... View full abstract»

  • Optimising bistatic HF radar configurations for target and environmental signature discrimination

    Publication Year: 2007, Page(s):29 - 33
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2034 KB) | HTML iconHTML

    HF radars are large and expensive systems whose performance is strongly dependent on the scattering geometry. There have been several cases where such radars have been poorly deployed, with consequent failure to achieve the surveillance objectives. This paper formulates the problem of radar site configuration in terms of objective mission-related metrics and outlines the optimisation procedure. View full abstract»

  • Adaptive estimation of unknown phase offset between sub-arrays in distributed aperture systems

    Publication Year: 2007, Page(s):34 - 36
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (207 KB) | HTML iconHTML

    It has been recently shown that angle-dependent complex phase and gain offsets between separately calibrated distributed subarrays can be compensated for during beamforming via a modification of a subspace detection approach. In addition to normal estimation and detection losses associated with such an adaptive filter, an additional loss is incurred using this approach. This loss is derived analyt... View full abstract»

  • Acoustic scattering problems and smart obstacles

    Publication Year: 2007, Page(s):37 - 40
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (246 KB) | HTML iconHTML

    We study smart obstacles in acoustic scattering. Smart obstacles are obstacles that when hit by an incoming acoustic wave react in order to pursue a preassigned goal such as, for example, to be furtive. We propose a control problem for the wave equation as mathematical model of the behaviour of the smart obstacles. The mathematical model proposed is solved in some test cases with satisfactory resu... View full abstract»

  • Angle-Only Tracking of Manoeuvring Targets using Double Sets of Multiple Range Models and Probability Mass Diffusion

    Publication Year: 2007, Page(s):41 - 46
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (169 KB) | HTML iconHTML

    This paper presents a solution to the problem of tracking of manoeuvring targets by angle-only measurements from a single, manoeuvrable platform. The solution combines the properties of accurate range estimates of non-manoeuvring targets with the ability to track manoeuvring targets in an all recursive setting. While previous methods use combinations of recursive and batch processing and/or thresh... View full abstract»
