In modern conditions of active use of unmanned aerial vehicles (UAVs) for solving the tasks of reconnaissance, monitoring, transmission of useful data in the form of telemetry and video images in real time, the reliability of radio communication between the UAV and the ground control point (GCP), especially in conditions of deliberate interference and the use of electronic countermeasures (ECM), is of particular relevance. This article contains the results of the development of a radio modem based on software-defined radio technology for wireless communication systems with unmanned aerial vehicles. The aim of article is to develop, manufacture and experimentally debug a radio modem based on software-defined radio technology as part of a wireless communication system for UAVs. The article presents the results of the development of a radio modem based on the software-defined radio technology from a set of wireless communication tools and its experimental testing. The dependences of the radio modem's throughput and its receiving channel sensitivity on various types of manipulation and coding speed are investigated. The stability of data transmission is investigated and the delays in transmitting control signals, telemetry and UAV position data are determined during parallel transmission of video data via a radio channel and during signal retransmission. The developed radio modem based on software-defined radio technology can be successfully applied in radio communication systems to ensure information interaction between UAVs and GCP.
