Developing a Virtual Device to Identify Signals for Aviation Communication Monitoring System

Rapid loading of the used-frequency bands inevitably leads to an increase in the number of unintended interferences related to the system operation features. Also, there exists a danger of unapproved access to the professional communication frequency band. This is most critical for the metric-wave band, because it is here, where the main communication between an aircraft and the ground control occurs at the take-off and the landing. Data losses, in this case, may lead to a terrain accident, because the take-off and the landing are the most complex flight stages demanding prompt information exchange. Due to this, it is important to quickly find and identify the preventing effect impeding the radio communication. The goal of this paper is to develop an algorithm for detecting and identifying the signals in the set band, based on analyzing their in-phase (I) and quadrature (Q) components, which enables to essentially increase air safety.
