Abstract

The present invention belongs to the technical field of digital information transmission, and discloses a recognition method of different types of barrage jamming and deception jamming. The method comprises the steps of performing bispectrum calculation on a received radar active jamming signal to obtain a bispectrum of the jamming signal; respectively calculating Renyi entropies of the bispectrumunder different parameters, and combining the Renyi entropies into new feature vectors; and classifying the constructed feature vectors by using an RBF neural network classifier. When a jamming-to-noise ratio is greater than 0dB, recognition rates of amplitude modulation noise jamming and radio frequency noise jamming are 100%, when the jamming-to-noise ratio is greater than 3dB, a recognition rate of frequency modulation noise jamming is 95% or above and gradually approaches 100%; and recognition rates of three types of deception jamming rapidly grow up along with increase of the jamming-to-noise ratio, when the jamming-to-noise ratio is greater than 5dB, the recognition rates of the three types of deception jamming are all 94% or above and gradually approach 100%, and the method still has a good recognition effect for the deception jamming.

Description

technical field [0001] The invention belongs to the technical field of digital information transmission, and in particular relates to a method for identifying different types of covering interference and deceptive interference. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: radar active jamming is usually a radar jammer that deliberately interferes and hinders target detection and acquisition of target information. Radar active jamming identification technology is one of the important technologies in the field of electronic reconnaissance and radar anti-jamming. Electronic countermeasures play an increasingly important role in modern warfare. Radar jamming signal identification and analysis technology is the basis and guarantee for the effective work of electronic countermeasure equipment. With the rapid development of electronic technology, active radar jamming has become a powerful radar countermeasure and ha...
