//input data
Pt = 500*10^3;//peal pulse power in watts
Pmin = 1*10^-12;//minimum receivable power
Ac = 5;//area of capture in m^s
RCS = 20;//radar cross sectional area in m^2
F = 10*10^9;//radar operating frequency
Vo = 3*10^8;//vel of Em wave in m/s;
lamda = 3*10^-2;//wavelength in cms
//calculations
Rmax = ((Pt*Ac*Ac*RCS)/(4*%pi*lamda*lamda*Pmin))^0.25;
//output
mprintf('Maximum Radar range of the Radar system is %g Kms',Rmax/1000);
