//Variable Declaration
El=50 //Elevation Angle(degrees)
h0=0.6 //Earth station altitude(km)
hr=3 //Rain height(km)
R01=10 //Point Rain Rate(mm/hr)
f=12 //frequency(GHz)
ah=0.0188

//Calculation
Ls=(hr-h0)/sin(El*3.142/180) //Slant path length(km)
LG=Ls*cos(El*3.142/180) //Horizontal projection(km)
r01=90/(90+4*LG) //Reduction factor
L=Ls*r01 //Effective path length(km)
alphah=ah*R01**bh //Specific Attenuation
AdBh=alphah*L //Rain Attenuation for horizontal polarization
alphav=av*R01**bv //Specific Attenuation
AdBv= alphav*L //Rain Attenuation for vertical polarization
//Results
