Track-before-detect strategies for range distributed target detection in compound-Gaussian clutter

This paper considers range distributed target detection in compound-Gaussian clutter, which is often arisen in high resolution radars. Two dynamic programming based track-before-detect (DP-TBD) strategies, i.e., noncoherent integration based DP-TBD (NCI-DP-TBD) and the generalized likelihood ratio test based DP-TBD (GLRT-DP-TBD) strategies, are proposed to address the detection problem. The detection performances of the proposed strategies are examined via numerical simulations. HighlightsRange distributed targets in compound-Gaussian clutter is considered.Noncoherent integration and GLRT based DP-TBD strategies are proposed.A covariance matrix estimation strategy is proposed.
