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. A combined plot spectrum is formed as a vector of range reports from the matrix, which is initiated with the range cell of the plot centroid and then the next nearest range report in adjacent range cells is inserted at all burst positions at which there is no range report in the range cell. Remaining gaps are filled with the adjacent Doppler filter amplitudes of the range reports used and then gaps still remaining are filled with a suitable noise value.
