Abstract: This application provides radar ranging method and apparatuses. In an implementation, a method comprises: sending a first radar signal through a first transmitter, receiving a first echo signal of the first radar signal through a first receiver, wherein the first echo signal comprises an echo signal of a first target, receiving a second echo signal of the first radar signal through a second receiver, wherein the second receiver is located outside a primary signal transmission path between the first transmitter and the first receiver, wherein the second echo signal is used to determine a target spurious echo signal corresponding to an obstacle, and wherein the echo signal of the first target and the target spurious echo signal are different signals, and performing ranging processing on the first target based on the first echo signal and the second echo signal.

Abstract: This application is applied to the autonomous driving field, and provides a signal receiving apparatus, a detection apparatus, and a signal processing method and apparatus. The receiving apparatus includes a first receiving branch; the first receiving branch includes a first detector and a signal coupling apparatus; the first detector is configured to output one branch of echo electrical signal; the signal coupling apparatus outputs at least two branches of echo electrical signals based on the branch of echo electrical signal output by the first detector; and one branch of echo electrical signal in the at least two branches of echo electrical signals has same signal strength as the branch of echo electrical signal output by the first detector.
