2) (20 points) The frequency modulation pattern of a FMCW radar is given below. The center frequency of operation for the radar is 3 GHz. For a target that is 30 km away from the radar and aprroching with 2 m/s radial speed; 3.0001 GHz - 2.9999 GHz ... 0.5 ms I ms 1.5 ms Figure (a) Figure (b) a. (6 pnts) Calculate the Doppler frequency and the delay of the echo signal received from the target. b. (9 pnts) Draw the time-frequency response of the echo signal on Figure (a) and the temporal variation of the beat frequency on Figure (b) given below. c. (5 pnts) Is it possible to find the range frequency from Figure (b)? Explain your
