ADS-B-based radiation source individual identification method and device

Abstract

The invention belongs to the technical field of signal processing, and particularly relates to an ADS-B-based radiation source individual identification method and device, and the method comprises thesteps of obtaining an ADS-B pulse signal periodically broadcasted by a transponder in a working state, wherein the ADS-B pulse signal comprises a frame header and a data part; extracting individual characteristic parameters of the preamble pulse, decoding the data part to obtain individual identity information, and forming a characteristic vector by the individual characteristics and the individual identity information; dividing the feature vectors into a training data set and a test data set which are used for training a test neural network classifier; and for the target signal, carrying outradiation source individual identification by using the trained neural network classifier. According to the method, the operation complexity is reduced, and the problems of difficulty in individual information verification, low reliability due to pure dependence on simulation signals and the like in individual recognition are effectively solved. By means of the advantages of FPGA parallel computing and software decoding flexibility, the rapid and efficient decoding of the ADS-B messages is achieved, and the method has the important guiding significance for development of the radar radiation source individual recognition technology.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to an ADS-B-based radiation source individual identification method and device. Background technique [0002] Individual radar emitter identification is an important part of the electronic reconnaissance system, which can realize the association of "signal-radiator individual", so as to accurately lock threat sources or high-value targets, and achieve the purpose of "scalpel" fixed-point elimination. Individual identification technology is not only of great significance in military applications, but also has high value in the fields of civilian network security access, cognitive radio, and public safety. A large number of research institutions at home and abroad have carried out research on the individual identification technology of radar radiation sources. In the research on radar individual identification technology, the conclusion of unintentional phase mo...
