Abstract

The invention belongs to the technical field of methods or devices applying electronic equipment for recognition, and discloses a target radiation source individual recognition method. The target radiation source individual recognition method comprises the steps that a received target radiation source signal is subjected to empirical modal decomposition and variational modal decomposition to obtain different modal components; each intrinsic modal component is denoised through singular spectral analysis, and multi-scale arrangement entropy of each modal component is calculated to construct feature vectors; and the feature vectors are subjected to dimensionality reduction through principal component analysis, and target radiation source individual recognition is achieved through a support vector machine classifier. Target radiation source individual recognition under an environment with the lower signal-to-noise ratio can be effectively achieved, and pretreatment such as signal-to-noiseratio estimation is not needed.

Description
