Radio control transmissions

A radio control (RC) vehicle, e.g. drone, travelling in a predefined zone is detected 710 by scanning frequencies of radio frequency (RF) signals, measuring RF power in frequency bands of the scanned frequencies and generating a temporal RF signature based on the measured RF power. A frequency hopping scheme of a RC communications protocol used by the RC vehicle is determined 725, and a timing and an order of the frequency hopping scheme is determined 730 to produce an RC signature of the RC vehicle. The RC vehicle may be engaged by transmitting interfering RF signals at a precise frequency and timing as the frequency hopping scheme exhibited by the RC vehicle 740 and/or by seizing control of the RC vehicle by injecting one or more data packets to control the vehicles travel or disrupt normal communication of the RC vehicle to disable remote control between the RC vehicle and its operator.
