Abstract
Taking into account the sensing-pulse frequency chirp, we have derived generalized algorithms for recovering the non-uniform Doppler-velocity coherent-lidar profiles within the lidar resolution interval conditioned by the pulse length. The laser pulses are assumed to have an exponentially shaped form. The performance and the efficiency of the algorithms obtained are studied and illustrated by computer simulations. It is shown that in the presence of arbitrary, in form and magnitude, but known regular frequency chirp, at some reasonable number of signal realizations and appropriate data processing to suppress the noise effects, the Doppler-velocity profiles can be determined accurately with considerably shorter resolution scale compared with the pulse length.
