Abstract

Based on the time-domain simulation model of coherent wind measurement, it is deduced that the detected atmospheric backscattered spectrum is a two-dimensional convolution of the real atmospheric information, and the instrument point spread function. The spatial resolution can be improved by applying the image deconvolution algorithm to the inversion of the Coherent Wind Lidar (CWL) signal. The effect of the deconvolution algorithm in improving spatial resolution is compared in simulation and experiment. The results show that the spatial resolution can be improved effectively by using the deconvolution algorithm when the transmitted pulse waveform is known.
