Assume that we have a horizontal \(10 \mathrm{~km}\) laser link at height \(h_{0}\) above the ground where the Fried parameters for the air and ground terminals are given by

respectively. Assume that the refractive index structure parameter at altitude is

Let the wavelength equal \(1.55 \mu \mathrm{m}\) and the air and ground receiver aperture diameters be \(10 \mathrm{~cm}\). What is the value of the two Fried parameters? What is the approximate value of the two Strehl ratios?
