Abstract

A feuilleté model for assessment of the performance of heterodyne coherent laser radar 1HCLR2 under nonstationary atmospheric conditions such as wind shear and a fine layering of scattering properties is proposed. The model is an end-to-end signal simulation in the time domain at intermediate frequency from beam propagations to signal processing. The model takes into account the full transverse dimension of the problem of laser–atmosphere interaction. The scatterers are grouped into slices, then an integration is performed over the slices that contribute to the HCLR signal. Two applications are presented: wind-shear detection for 10-μm HCLR and wind-vortex detection for 2-μm HCLR.
