Title:
ECHO SIGNAL PROCESSING METHOD, APPARATUS AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/237448
Kind Code:
A1
Abstract:
An echo signal processing method, apparatus and system, and a storage medium. The method comprises: determining, on a current data frame, a first pixel within a receiving field of view of a radar and N sampling point sets on an echo signal corresponding to the first pixel (S201); estimating an estimated distance between the radar and a target object according to each first sampling point set in the N sampling point sets, and determining M cumulative receiving fields of view corresponding one-to-one to M data frames according to each estimated distance (S202); determining a second sampling point set on echo signals corresponding to Q neighbor pixels in the M cumulative receiving fields of view according to each first sampling point set, and superposing each first sampling point set and the corresponding second sampling point set so as to obtain an echo signal that has undergone superposition and that corresponds to the first pixel (S203); and calculating the actual distance between the radar and the target object according to the echo signal that has undergone superposition (S204). The described method improves the signal-to-noise ratio of echo signals by means of implementing inter-frame signal multiplexing, thereby improving ranging accuracy.
