2.37. A CW radar uses linear frequency modulation to determine both range and range rate. The radar wavelength is =3cm, and the frequency sweep is Af=200KHz. Let to = 20ms.

(a) Calculate the mean Doppler shift;

(b) compute fb, and fbd corresponding to a target at range R = 350Km, which is approaching the radar with radial velocity of 250m/s.
