A certain target has the following characteristics: its range away from the radar, given in its corresponding \(x^{-}, y^{-}\), and \(\mathrm{z}\)-components, is \(\{25,32\), and \(12 \mathrm{~km}\}\). The target velocity vector is \(v_{z}=v_{y}=0\), and \(v_{x}=-250 \mathrm{~m} / \mathrm{s}\). Compute the composite target range and range rate. If the radar's operating frequency is \(9 \mathrm{GHz}\), what is the corresponding Doppler frequency?
