The invention discloses a recognizing and classifying method for
broadband radar interference signals. The method comprises the following steps of S1, obtaining
radar interference signals, processingthe signals, and obtaining
digital video signals; S2, performing short-time Fourier conversion on the
digital video signals, and obtaining a time
frequency matrix; S3, according to a
ranking statistics constant false-alarm method,
processing the time
frequency matrix, and obtaining a constant false-alarm detection matrix; S4, calculating parameters of interference signals in the constant false-alarm detection matrix, and integrating the parameters of the interference signals into a
signal parameter matrix, and obtaining an interference
signal detection result; S5, according to the interferencesignal detection result, calculating interference
signal characteristics; S6, according to the interference signal characteristics, recognizing and classifying the interference signals. According tothe interference-based time-frequency signal characteristics, nine
broadband radar interferences are recognized and classified, and the method has the capability of multi-interference (non-overlappedon frequency) classifying and recognizing.
