A certain radar has range resolution of \(300 \mathrm{~m}\) and is observing a target somewhere in a line of high towers each having RCS \(\sigma_{\text {tower }}=10^{6} \mathrm{~m}^{2}\). If the target has RCS \(\sigma_{t}=\) \(1 \mathrm{~m}^{2}\), (a) how much signal-to-clutter ratio should the radar have? (b) repeat part (a) for range resolution of \(30 \mathrm{~m}\).
