The application discloses a frequency-modulated continuous wave radar noise reduction ranging method based on weighted normalization, mainly solves the problem of inaccurate frequency-modulated continuous wave radar ranging under frequency-modulated continuous wave interference and white noise background, and introduces a weighted normalization algorithm into a radar ranging framework, and proposes a radar noise reduction ranging method based on envelope weighted normalization.Under a traditional linear frequency-modulated continuous wave radar ranging model, a method of performing weighted normalization processing on a radar echo envelope interfered by noise is designed, compared with traditional linear frequency-modulated continuous wave radar ranging, the application can effectively reduce the influence of frequency-modulated continuous wave and white noise superimposed interference on the echo amplitude of the frequency-modulated continuous wave radar ranging signal, and effectively improves the ranging precision in combination with constant false alarm threshold detection.
