18. Depolarization

18.1 Lidar depolarization ΔL(r)

The depolarization of the backscattered light is measured by separating the polarization-parallel and polarization-perpendicular components of the probing laser radiation at the receiving end, using a polarizing element.

The two LRAN signals are written :

\begin{array}{l} s_{L, ∥} (r) r^{2} = K_{∥} [β_{π, p, ∥} (r) + β_{π, m, ∥} (r)] T_{m}^{2} (0, r) T_{p}^{2} (0, r) \\ s_{L, ⊥} (r) r^{2} = K_{⊥} [β_{π, p, ⊥} (r) + β_{π, m, ⊥} (r)] T_{m}^{2} (0, r) T_{p}^{2} (0, r) \end{array}
