Abstract
An apparatus includes a video encoder, a camera and radio frequency modulation circuitry. The radio frequency modulation circuitry is operative to modulate a radar signal to include video data. A radar transmitter is operatively coupled to the radio frequency modulation circuitry, and is operative to transmit a radar signal including the video data. The apparatus may also include radio frequency demodulation circuitry and a video decoder. The video decoder is operative to decode video data contained in a radar signal demodulated by the radio frequency demodulation circuitry. An inter-vehicle alert system controls the camera to initiate capturing video data which includes the video data. A method of operation modulates a radar signal to include at least a portion of the video data captured in response to detecting an obstruction, and transmits the radar signal to a second vehicle via an antenna array oriented at the moving vehicle's rear.
