SIGNAL PROCESSING METHOD AND RELATED DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/129388

Kind Code:

A1

Abstract:

Provided are a signal processing method and a related device, particularly relating to a laser radar. The method comprises, reflecting a first laser to a detection area through a scanning reflection module at a first angle (S201); determining a first summed electrical signal according to at least two electrical signals coming from at least two detection units (S202), wherein the first summed electrical signal comprises at least one characteristic signal; determining at least one target distance corresponding to the detection area according to time information of the at least one characteristic signal (S203); determining at least one detection unit group according to the at least one target distance and the first angle (S204), wherein the detection unit included in the detection unit group in the at least one detection unit group belong to the at least two detection units; and determining at least one echo information in the detection area according to the first electrical signal obtained from the at least one electrical signal of the first detection unit group in the at least one detection unit group (S205). The method and device can reduce interference of irrelevant signals in the radar echo information and improve signal-to-noise ratio of the received signal.
