1. The problem statement, all variables and given/known data

What must be the frequency bandwidth of the detecting and amplifying steps of a radar system operating at pulse widths of 0.1usec? If the radar is used for ranging (distance measurements), what is the uncertainty in the range?

2. The attempt at a solution

Aside from knowing that this is an extension of discussion on particles as wave packets, I have no idea where exactly to start on this problem. I'm assuming some form of wave function will need to be utilized? Any suggestions of an angle of attack here are welcome.

What is the bandwidth of an amplitude modulated radio signal modulated at a frequency $f = \omega/2\pi = 10^{7} sec^{-1}$ ?
