Homework Statement



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} ?

Thread 'Modeling a graph that shows age in relation to depth of an ice sample'

To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
