Title:
FREQUENCY MODULATED CONTINUOUS WAVE RADAR AND SELF-DETECTION METHOD FOR LONGITUDINAL MODE STATE OF LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2024/087891
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a frequency modulated continuous wave radar and a self-detection method for a longitudinal mode state of a light source. The frequency modulated continuous wave radar comprises: a light source suitable for transmitting a frequency-modulated optical signal in a preset period, wherein at least one period is a self-detection period, and the frequency-modulated optical signal transmitted by the light source in the self-detection period is a self-detection signal; and a detection module suitable for detecting the self-detection signal so as to determine the longitudinal mode state of the light source. By using the solution, the detection of the longitudinal mode state of the light source of the frequency modulated continuous wave radar can be realized without an external device, so that the detection cost is reduced, and the detection efficiency is improved.
