moving target detection in airborne widely separated phased mimo radar using generalized subspace detector

in this paper, the detection of moving targets in airborne widely separated phased multiple input multiple output (mimo) radars which are located on moving platform is investigated. in order to derive the detector, the generalized likelihood ratio test is applied. the proposed detection rule, exploits the clutter subspace information and its maximum likelihood estimation, to improve the detection performance in strong clutter background. first, we have proposed as an innovation, space-time signal model for widely separated phased mimo radar with arbitrary configuration of antenna position in three dimensional space. moreover, the generalized likelihood ratio detector for moving target detection in presence of structured clutter has derived and it is shown that the proposed detection rule has constant false alarm rate property. simulation results are provided to demonstrate the performance of the proposed detector in different scenarios.
