Abstract
Abstract
Pulse echo accumulation is commonly employed in coherent Doppler wind LiDAR under the assumption of steady wind. Here, the measured spectral data is analyzed in the time and frequency dimensions to cope with the temporal wind shear and achieve the optimal accumulation time. A hardware-efficient algorithm combining the interpolation and cross-correlation is used to enhance the wind retrieval accuracy by reducing the frequency sampling interval and then reduce the spectral width calculation error. Moreover, the temporal and spatial broadening effects are decoupled according to the strategy we developed.
