SIGNAL RECEIVING DEVICE, DETECTING DEVICE, AND SIGNAL PROCESSING METHOD AND DEVICE

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. The signal coupling apparatus adds one branch of or more branches of echo electrical signals without changing the branch of echo electrical signal output by the first detector. This improves accuracy of signal processing. Compared with using only one branch of echo signal, this enlarges a dynamic detection range. The method may be applied to the Internet of Vehicles, for example, vehicle-to-everything V2X, long term evolution-vehicle LTE-V, and vehicle-to-vehicle V2V.
