WebTo estimate the Doppler shift associated with each target, we need to find the locations of the peaks in each Doppler spectrum. In this example, the targets are present at two different ranges, so the estimation process needs to be repeated for each range. Let's first plot the Doppler spectrum corresponding to the range of 2000 meters.
