A method for controlling a wind turbine, comprising: receiving signals representative of oncoming wind speeds approaching at least a portion of a wind turbine; receiving background noise and signals representative of signal-to-noise ratios corresponding to the signals representative of the oncoming wind speeds; determining an availability-and-atmospheric noise in the signals representative of the oncoming wind speeds based on one or more of the signal-to-noise ratios, blade positions of blades of the wind turbine, and a yaw position of a nacelle of the wind turbine; determining a wind incoherence noise in the signals representative of the oncoming wind speeds due to a change in the oncoming wind speeds while approaching at least the portion of the wind turbine; determining a net measurement noise in the signals representative of the oncoming wind speeds based on the background noise, the availability-and-atmospheric noise, and the wind incoherence noise; and controlling the wind turbine based at least on the signals representative of the oncoming wind speeds and the net measurement noise, wherein determining the wind incoherence noise comprises: determining a plurality of cross-correlation coefficients corresponding to a plurality of distances between the plurality of range locations; determining a plurality of regression coefficients based on the plurality of cross-correlation coefficients and the plurality of distances between the plurality of range locations; determining coherence loss based on the plurality of regression coefficients and the plurality of distances between the plurality of range locations; and determining the wind incoherence noise based on the coherence loss. receiving signals representative of oncoming wind speeds approaching at least a portion of a wind turbine; receiving background noise and signals representative of signal-to-noise ratios corresponding to the signals representative of the oncoming wind speeds; determining an availability-and-atmospheric noise in the signals representative of the oncoming wind speeds based on one or more of the signal-to-noise ratios, blade positions of blades of the wind turbine, and a yaw position of a nacelle of the wind turbine; determining a wind incoherence noise in the signals representative of the oncoming wind speeds due to a change in the oncoming wind speeds while approaching at least the portion of the wind turbine; determining a net measurement noise in the signals representative of the oncoming wind speeds based on the background noise, the availability-and-atmospheric noise, and the wind incoherence noise; and controlling the wind turbine based at least on the signals representative of the oncoming wind speeds and the net measurement noise, wherein determining the wind incoherence noise comprises: determining a plurality of cross-correlation coefficients corresponding to a plurality of distances between the plurality of range locations; determining a plurality of regression coefficients based on the plurality of cross-correlation coefficients and the plurality of distances between the plurality of range locations; determining coherence loss based on the plurality of regression coefficients and the plurality of distances between the plurality of range locations; and determining the wind incoherence noise based on the coherence loss. determining a plurality of cross-correlation coefficients corresponding to a plurality of distances between the plurality of range locations; determining a plurality of regression coefficients based on the plurality of cross-correlation coefficients and the plurality of distances between the plurality of range locations; determining coherence loss based on the plurality of regression coefficients and the plurality of distances between the plurality of range locations; and determining the wind incoherence noise based on the coherence loss.
