[x,dx] = EqualCn2Screens([n],Atm,[Nscreens],[Geom])
Calculates pathnormalized phase screen positions and thicknesses for equal strength phase screens. This function first calculates the plane wave coherence length, $r_0^{5/3}$, and divides by Nscreens so that each segment will have the same strength. This function discretizes the calculation by breaking the path into n segments per meter and integrating $C_n^2$ to reach the desired strength per phase screen. If Atm.MaxAlt is not infinite, output screen positions are over the path where altitude is less than Atm.MaxAlt as assumed by AtmStruct.
Parameters 
Description 
n [scalar] 
(Optional) Number of screens for discretizing the calculation. Defaults to Nscreens and is increased as needed. 
Atm [struct/string] 
Atmospheric modeling parameters. Can be a structure from AtmStruct or a turbulence profile model to be used. 
Nscreens [scalar] 
(Optional) Number of phase screens to calculate. If Atm is a discrete structure from AtmStruct and Nscreens is not specified, Nscreens will be the number of screens in Atm. 
Geom [struct/list] 
Geometry parameters. Can be a structure from GeomStruct or a comma separated list of (hp,ht,rd,...)  not required if Atm is a structure from AtmStruct. 
hp [scalar] 
Altitude of transmit/receive platform (m) 
ht [scalar] 
Altitude of target (m) 
rd [scalar] 
Downrange of target along spherical earth surface (m) 
Return Values 
Description 
x [vector] 
Pathnormalized phase screen positions 
dx [vector] 
Pathnormalized phase screen thicknesses
