Consider a synthetic aperture radar. You are given the following Doppler history for a scatterer: {1000 Hz, 0, –1000 HZ}, which corresponds to times {–10 ms, 0, 10 ms}. Assume that the observation interval is Tob = 20 ms, and a platform velocity v = 200 m/s. 

(a) Show the Doppler history for another scatterer which is identical to the first one except that it is located in azimuth 1 m earlier. 

(b) How will you perform deramping on the quadrature components (show only the general approach)? 

(c) Show the Doppler history for both scatterers after deramping.
