Abstract: Classification of radar objects involves processing a received radar signal in an input channel within a number of successive coherent integration intervals (bursts), detecting an object using Doppler filter amplitudes, and producing range reports. A number of range reports are combined using a cluster algorithm to form a plot, and adding Doppler filter amplitudes of the two azimuthally adjacent bursts from the same range cell each range report. As subset of the range reports is formed by, starting with the range report at the position of a plot centroid, arranging range reports from a defined number of bursts sorted according to azimuthal position in a matrix of the dimension azimuth x range with the plot centroid in the center. Doppler filter amplitudes from the region plot centroid +? a defined number of bursts associated with the range reports are arranged according to the burst sequence.
