Abstract

The feasibilities of a new approach for improving the resolution of coherent Doppler lidars, compared with the known PP-estimator-based approach, are investigated by computer simulations in the case of rectangular laser pulses. This approach consists in employing inverse techniques for retrieving the Doppler-velocity profile on the basis of known pulse shape and estimated statistically autocovariance of the heterodyne-signal profile. The possibility is demonstrated to achieve a spatial resolution cell that is much shorter than the pulse length.
