Abstract

The invention provides a radiation source recognition method and a radiation source recognition device. The radiation source recognition method comprises the following steps: A, acquiring a first number of radiation source training signals, and using as a training sequence; B, gaining the Hilbert spectrum of the first number of radiation source training signals; C, gaining the correlation coefficients between the Hilbert spectrum of each training signal and the Hilbert spectrum of other training signals, and forming training vectors; D, training a classifier according to the training vectors and category marks corresponding to the training signals so as to distinguish different radiation sources; E, obtaining a second number of radiation source test signals, and using as a test sequence; F, gaining the Hilbert spectra of the second number of radiation source test signals; G, gaining the correlation coefficients between the Hilbert spectrum of each test signal and the Hilbert spectrum of other test signals, and forming test vectors; H, classifying the test vectors in the step G by the classifier, and distinguishing the radiation source of the test sequence. Dot-to-dot scenes can be expanded to relay scenes, so that each category of radiation sources is recognized.

Description

technical field [0001] The invention relates to the field of communication signal transmission, in particular to the technical field of analysis and identification of communication signal transmission characteristics. Background technique [0002] In the communication signal transmission system, there are various radiation sources. For different radiation sources, due to the differences in the production process and installation and debugging of its components (especially power amplifiers), the system will produce different nonlinear characteristics and affect the signal on the system, so the radiation emitted by the radiation source The signals carry subtle features that identify differences in the emitter hardware, known as emitter fingerprints. Emission source identification (specific emitter identification, SEI) is a technology that extracts radiation source fingerprint features from received signals to distinguish different radiation sources. Radiation source identifi...
