A method and apparatus for scanning a road environment based on a frequency modulated continuous wave radar

摘要

Here, a method and apparatus for detecting a road environment based on a FMCW radar is disclosed. A method for detecting a road environment based on an FMCW radar comprises the steps of: performing a first scan with the FMCW radar to detect a first frequency spectrum of beat signals and shifting the first frequency spectrum based on first speed information of a vehicle (600) in performing the first scan; Performing a second scan on the FMCW radar to detect a second frequency spectrum of beat signals and shifting the second frequency spectrum based on second speed information of a vehicle (600) in performing the second scan; Obtaining correlation information between the shifted first frequency spectrum and the shifted second frequency spectrum and comparing the correlation information with a predetermined threshold and detecting the road environment.
