//input data
Pt = 20*10^6;//peak pulse power in watts
RCS = 1;//radar cross sectional area in m^2
f = 3*(10^9);//radar operating frequency
Vo = 3*(10^8);//vel of Em wave in m/s;
D = 50;//diameter of antenna in m
F = 2;//receiver noise figure
BW = 5000;//receiver bandwidth
//calculations
lamda = Vo/f//wavelength in m
Rmax = 48*((Pt*(D^4)*RCS)/(BW*lamda*lamda*(F-1)))^0.25;
//output
mprintf('Maximum Radar range of the Radar system is %g Kms\n ',Rmax/1000);
mprintf('Note:In textbook All values are correctly substituted in calculating Rmax.\n but incorrect final answer is printed in the book');
