MATLAB
ModelData = LEEDRAtm(G,[NScreens],[lambda])
Description

Generates an Atm structure using all LEEDR data. LEEDR data must be loaded and available in application data - see loadLEEDRAtmos.

Parameters
Parameters 
Description 
Geom [struct/list] 
Geometry parameters. Can be a structure from GeomStruct or a comma separated list of (hp,ht,rd,...) 
hp [scalar] 
Platform altitude (m AGL) 
ht [scalar] 
Target altitude (m AGL) 
rd [scalar] 
Downrange along spherical earth surface (m) 
NScreens [scalar] 
(Optional) Number of equal thickness phase screens. Screens are spaced symmetrically about the midpoint of the propagation path. For a continuous model use NScreens=Inf 
lambda [scalar] 
(Optional) Desired wavelength for computation of absorption, scattering, and extinction (m). If this wavelength does not match the wavelength in the precomputed data, LEEDR will be re-run. If not input, will use the first wavelength in the LEEDR data. 
Return Values
Return Values 
Description 
Atm [struct] 
Structure containing atmospheric screen parameters 
Examples

  • Atm = LEEDRAtm(GEOM,10,1e-6)
    • Generate Atm using LEEDR data with extinction at 1e-6 m wavelength
  • Atm = LEEDRAtm(GEOM,10)
    • Generate Atm with extinction at the wavelength of the LEEDR data
