SphericalWaveStrFcn

MATLAB

D = SphericalWaveStrFcn(alpha, d, Atm, wvl)

Description

Computes the wave structure function for a spherical wave in units of rad^2 given turbulence multiplier alpha, point spacings d, atmospheric modeling data in Atm, and wavelength in wvl. In this calculation, the light propagates from the target to the platform.

Parameters

Parameters	Description
alpha [scalar]	Turbulence strength multiplier.
d [vector]	Separation of the points in the aperture plane (m).
Atm [struct]	Atmospheric modeling structure from AtmStruct.
wvl [scalar]	Optical wavelength (m).

Return Values

Return Values	Description
D [vector]	Structure function value (${rad}^2$)

Examples

>> Atm = AtmStruct(0, 2e4, 0, 100, 'Cn2', 'HV57');

>> d = linspace(0, 0.5, 30);

>> D = SphericalWaveStrFcn(1, d, Atm, 0.5e-6);

Wave structure function value for turbulence multiplier of 1, wavelength 0f 500 nm, point source at 20 km propagating straight down, separation vector d, and atmospheric model Atm.
