METHOD FOR PROCESSING A SIGNAL FROM A COHERENT LIDAR TO REDUCE NOISE AND ASSOCIATED LIDAR SYSTEM

摘要

A method for processing (80) a signal from a coherent lidar comprising a coherent source (L), the method comprising the steps of: -generating (100, 110) a first beat signal ( Sb1) and a second beat signal (Sb2) respectively from a first detection set (D1) and a second detection set (D2 - for a plurality of n time intervals (ti), determine (120) n respective spectral density values (DSPi) from a frequency-domain transform of the cross-correlation between the first and the second beat signal, -determining (130) a mean value (DSP) of the spectral density from said n spectral density values (DSPi), -determining (140) target location information from the average value of said spectral density.
