Interception of a Radio-controlled Model by Means of a Software-defined Radio and GNU Radio Companion

Recently, the technologies of software-defined radio are becoming increasingly applied. The development of SDR technology and its availability allow us to develop our own software and hardware complexes, including using SDR to intercept radio control. The article will present the implementation of the interception of the radio model control at a frequency of 40.8 MHz by means of the GNU Radio development environment, as well as the LimeSDR software-defined radio device. The article will present the process of detecting and recording a radio control signal, its subsequent decomposition and generation of its own signal with subsequent application in practice. The developed program was used in the framework of technological competitions in the direction of "Radio Interception".
