Abstract :
Information on the pulse repetition interval (PRI) modulation of a radar signal plays an important role in detecting and identifying each radar signal in an electronic warfare support (ES) system. In this paper, we present a new method for recognizing the PRI modulation type of a radar signal using symbolization. The proposed method uses three key feature parameters extracted from symbol sequences in order to discriminate each PRI modulation type. The recognition capability of the method presented is verified through extensive simulations.
