RADAR RANGING METHOD AND DEVICE

This application provides a radar ranging method and an apparatus, which may be applied to the field of sensor technologies, for example, the field of radar ranging, to improve accuracy of radar ranging. The method includes: sending a first radar signal from a first field of view through a first transmitter; receiving a first echo signal from the first field of view through a first receiver, where the first echo signal includes an echo signal of a first target, and the first transmitter and the first receiver belong to a first radar channel (S210); and performing ranging processing on the first target based on the echo signal of the first target, where the first echo signal further includes a spurious echo signal, the spurious echo signal includes an echo signal generated when the first radar signal is reflected by an obstacle, at least one first signal parameter of the spurious echo signal corresponds to an identifier of the first radar channel and/or the first field of view, and the at least one first signal parameter includes an amplitude at at least one first sampling moment and/or first delay time (S220).
