Method of Smart Noise Jamming Recognition Based on Box Dimension

Smart noise jamming is a valid mode to interfere the new system radar, which has the characteristics of both de.ceiving jamming and noise jamming, and its recognition has become a hot topic in electronic warfare. Aiming at threekinds of smart noise jamming, which are the convolution modulation smart noise jamming , the digital multidelay smartnoise jamming and the intermittent sampling repeater smart noise jamming, a method of smart noise jamming recognitionbased on box dimension is proposed by analyzing the generation principle and spectrum character. The support vector ma.chine is used to classify the jamming and the target. The simulation results show that this method has high recognition ac. curacy.
