Abstract
Systems and methods can support coprocessing radio signals and video to identify and locate a radio transmitter. Positions and orientations for cameras and RF sensors may be maintained. An RF signature associated with the radio transmitter may be received from the RF sensors to determine an RF persona. A first physical location for the radio transmitter may be estimated according to a physical radio propagation model operating on RF signals. A video stream from one or more of the cameras may be received. An individual may be identified in the video stream using computer vision techniques. A second physical location for the radio transmitter may be estimated from the video stream. Relationships may be established between the first physical location and the second physical location and between the RF persona and the identified individual. The relationships may be presented to an operator interface.
