1. A radar-sensing detection method based on radar-sensing communication integration, which is applied to a sending end, comprising:
determining a position of a receiving end based on a radar-sensing detection signal or a communication signal sent to the receiving end;
sending a beam control signal to the receiving end through a preset beam control request channel according to the position of the receiving end, wherein the beam control signal carries beam control information, and the beam control information comprises: frame control information, positioning request information, amount of data to be sent, beam occupation request information, channel occupation states, and spatial information check information; the frame control information is used to indicate demodulation information of the receiving end, and the positioning request information is used to broadcast vehicle information of the sending end itself, the beam occupation request information is used to request occupation of a spatial beam, the channel occupation states are used to inform the receiving end of an occupation state of a current channel, and the spatial information check information is configured for beam calibration;
receiving a beam control response signal sent by the receiving end, wherein the beam control response signal carries a sending delay and a sending channel frequency band, and the sending delay is used to indicate a sending time for a first detection result signal to be sent, the sending channel frequency band is used to indicate a sending channel frequency band for the first detection result signal, and the first detection result signal is a signal that is generated by the sending end after detecting surrounding environment and carries position information of all vehicles within a preset detection range of the sending end;
sending the first detection result signal to the receiving end in a preset reservation data channel according to the sending delay and the sending channel frequency band.
