摘要：

A novel jammimg identification method based on bispectrum analysis and fractal dimension is proposed to solve the recognition problem of smeared spectrum (SMSP) and chopping and interleaving (C&I) interferences. Firstly, three-dimensional bispectrum information is obtained by performing bispectrum analysis on radar echoes. Then a two-dimensional feature curve is generated to reduce the calculation cost by using a dimension reducing method. Finally, characteristic parameters of the box dimension and the information dimension are extracted from the two-dimensional feature curve and used as the sorting characteristics. In addition, a support vector machine (SVM) method is used to test the interference recognition rate. Simulation results show that the proposed method is stable and its identification rate is over 88% when the signal-to-noise ratio is 0 dB, verifying the effectiveness of the proposed method. © 2016, Editorial Office of Journal of Xi'an Jiaotong University.
