Algorithm for automatic recognizing of radar scan type, based on the extraction of statical features from input analyzed process

An algorithm for recognizing the radar antenna scan type by radio monitoring station is proposed. It is based on the extraction of a set of statistical features from the input radio signal, characterizing the signal amplitude envelope, modulated according to the scan type of radar antenna pattern. For feature extraction, mechanical, one-dimensional electronic and two-dimensional electronic scanning are considered, along with the beam steering schemes of radar antenna pattern used in practice. The essence of the proposed algorithm is the sequential comparison of the features with certain thresholds. The proposed recognition scheme is relevant for tasks of classifying the radio electronic equipment signals in a complex radio electronic environment and resolving ambiguity in recognizing radio signal sources with overlapping regions in the feature space, which characterizes time-frequency parameters of the radio signal. Experimental results are given, showing that the proposed algorithm ensures high recognition quality and is promising for improving existing and developing new radio monitoring equipment.
