    Space-time adaptive processing is attracting interest for use in airborne radars that detect low-flying aircraft and surface moving targets in the presence of clutter, jammers and other interference. This paper describes numerically robust and computationally efficient algorithms for STAP signal processing and their representation as systolic computational flow graphs. Their implementations using ... View full abstract»

    The detection of slowly moving targets by air- and spaceborne MTI radar is heavily degraded by the motion-induced Doppler spread of clutter returns. Space-time adaptive processing (STAP) can achieve optimum clutter rejection via implicit platform motion compensation. The fundamentals and properties of STAP applied to air- and spaceborne MTI radar are summarised View full abstract»

    The paper deals with the cancellation of clutter echoes in modern airborne early warning (AEW) radar systems equipped with digital beam-forming. The performances of reduced degrees of freedom (DoF) GLRT (generalised likelihood ratio test) detectors and the previously conceived nonlinear detector are compared. The nonlinear detector is demonstrated to be a compromise solution between computational ... View full abstract»

    Space-time adaptive processing (STAP) techniques provide simultaneous rejection of jamming and clutter in airborne radar. The greatest benefits over conventional MTI (moving target indication) approaches are in terms of a capability to detect slow-moving targets which possess the same Doppler frequency as mainlobe clutter returns. This paper examines the effects of platform manoeuvre on STAP clutt... View full abstract»

    Placing a radar in space for the detection and tracking of airborne moving targets has a number of advantages, however it creates a complex clutter environment and is susceptible to jamming. Both these problems can be solved by employing a space-time adaptive processor. This paper considers how space-time adaptive processing (STAP) can be applied and presents some simulation results illustrating i... View full abstract»

    This paper summarises a study of terrain-scattered interference (TSI) mitigation techniques, focusing on joint TSI mitigation and monostatic clutter nulling for airborne radars. It begins with an overview of TSI phenomenology and two-dimensional space-time adaptive processing (STAP) techniques for cancelling TSI. Two approaches for mitigating combined TSI and clutter are then examined. In the firs... View full abstract»

    Synthetic aperture radar (SAR) provides high-resolution images of a non-moving ground scene, but fails to indicate the presence and position of moving objects. As in airborne MTI (moving-target indication) systems the solution to this problem is to use an array of antennas or subapertures and several receiving channels (`MSAR', or multichannel SAR), and to apply multichannel clutter suppression. O... View full abstract»
