doppler shift= 2(relative velocity/wavelength)*Cos(depression angle).
here,
relative velocity = 300m/s
wavelength = (3*10^8)/10G
Cos60=0.5
hence doppler shift= 10K Hz
the second sum is just the same type, you have to take care to convert the speed in kts to m/s though.
for Janus array modify the formula as such: (4*relative velocity*cos dep angle*cos horizontal angle)/wavelength.
