1. A method, comprising:

  • processing, in an input channel within a number of successive coherent integration intervals, a received radar signal;

    performing, using Doppler filter amplitudes, an object detection;

    producing range reports;

    combining, using a cluster algorithm, a number of range reports to form a plot;

    adding Doppler filter amplitudes of two adjacent bursts of the number of successive coherent integration intervals from a same range cell to each range report;

    forming a subset of the range reports by, starting with a range report at a position of a plot centroid, arranging adjacent range reports from a defined number of bursts sorted according to azimuthal position in a matrix of a dimension azimuth x range with the plot centroid in a center of the matrix;

    arranging the Doppler filter amplitudes associated with the range reports from the region plot centroid+/−

    a defined number of bursts according to the burst sequence;

    forming a combined plot spectrum as a vector of range reports from the matrix, which is initiated with the range cell of the plot centroid;

    inserting a next nearest range report in adjacent range cells at all burst positions in a range cell at which there is no range report;

    filling remaining gaps with the adjacent Doppler filter amplitudes of the used range report; and

    filling any remaining gaps with a noise value.
