Abstract

The purpose of the article is the need to create a single portrait of a radioemission source and identification methods. Radiomonitoring tools are used to detect, identify and locate sources of radioemission in the coverage area. One of the important tasks solved by the radio monitoring system is the reception (interception) of transmitted messages on the air and signal identification. The article deals with the classification of the main parameters of radioemission sources, provides a classification of the modulation types and the main its parameters. The signal structure can be determined by autocorrelation and correlation methods. Autocorrelation is used to determine signal parameters such as the transmission duration, data block duration. Correlation allows to identify a specific signal from the set. To detect a radioemission source, two generalized algorithms are presented: recognition of the radioemission source type by unknown parameters and an algorithm for identifying a radiation source by given parameters. A simulation result of a radioemission source recognition algorithm with given parameters is presented; a linear frequencymodulated signature was used as a given signal. The result of the algorithm is a single outlier with full signal compliance, when the signals diverge, the outlier width increases, which indicates a discrepancy. This algorithm can be used to search for a given type of signal, which allows to increase the strip analysis speed and the detection accuracy. To increase the detection accuracy, it is recommended to use a combination of two algorithms with additional digital signal processing, which should lead to an increase in the accuracy of type of signal determining and a more rapid determination of the radiation source parameters.
