//input data
F = 6*10^9;//Transmitting Frequency of Radar
Vr = 250;//velocity of automobile in Kmph
Vo = 3*10^8;//velocity of EM wave in m/s
//Calculations
Va = Vr*(5/18)//velocity of automobile in m/s
Fd = (2*Va*F)/Vo//Doppler Frequency shift in Hz
//Output
mprintf('Doppler Frequency shift is %3.3f KHz',Fd/1000)
