Document Type and Number:
WIPO Patent Application WO/2024/071507
Kind Code:
A1
Abstract:
A frequency modulated continuous wave radar sensor according to an embodiment of the present invention may comprise: a signal generator for generating frequency modulated (FM) signals that change frequency over time; a transmission antenna for transmitting the FM signals generated by the signal generator; a reception antenna for receiving reflected signals of the FM signals reflected by an object; a frequency mixer which outputs the difference between the FM signals and the reflected signals; and a filter which extracts a mid-frequency component from the output of the frequency mixer.
