A certain radar is tasked with detecting and tracking the moon. Assume that the average distance to the moon is \(3.844 \times 10^{8} \mathrm{~m}\), and its average radar cross section is \(6.64 \times 10^{11} \mathrm{~m}^{2}\). (a) Compute the delay to the moon. (b) What is required PRF so the range to the moon is unambiguous? (c) What is the moon's radar cross section in \(d B s m\) ?
