Abstract
A first device sends a first message to a second device, where the first message indicates to the second device to hop to different channels at different times to send radio signals. The frequency bandwidth ranges of any two channels do not completely overlap, and the frequency bandwidth range of each channel is within a total frequency bandwidth range supported by the first device. The first device separately receives the radio signals that are sent by the second device on different channels at different times. The radio signals reach the first device after being reflected by an intermediate object. The first device measures the state information of the intermediate object based on the physical characteristics of the different radio signals that are separately received.
