摘要：

Based on the study on the feature of satellite navigation interference recognition and the higher-order cumulants' suppression effect to Gaussian noise, a feature recognition algorithm using 4th-order & 6th-order cumulants is proposed, and the eigen-interval distribution under the condition of different jamming noise ratios & different jamming signals are analysed. According to the separability of different jamming signals under the same recognition feature, a tree-like classifier using higher-order cumulants is designed. The experiments show that the classifier possesses 100% correct recognition rate to 9 jamming signals when the jamming noise ratio is 5 dB, and the results change little under different jamming noise ratios. The tree-like jamming classifier has good recognition performance.
