AeroOpticsScaling
[opdScaling,frqScaling,dimScaling] = AeroOpticsScaling(hp,vp, ...
Dt,lambda,hp0,vp0,Dt0,lambda0)Returns aero-optics scaling factors as function of platform altitudes, velocities, and turret diameters. Allows for vectorized inputs, but each nonscalar input must be of the same length. Outputs will then be vectors of the same length as the input vectors. If scaling from non-dimensionalized form, only the final platform altitude, velocity, turret diameter and wavelength need to be specified as inputs. If scaling from one set of (hp0,vp0,Dt0,lambda0) to a new set of (hp,vp,Dt,lambda), all eight input values should be specified.
