1. The problem statement, all variables and given/known data Pulse radar: Parameters: Carrier frequency: 5.3*10^9 Hz Pulse length: 20*10^-6s PRF: 30*10^6Hz 2. Relevant equations The question is this: "100 pulses are reflected from a moving target and received by the radar. -What is the resolution of a speed measurement determined from these measurements? -Can a speed of 100 km/h be measured unambiguously? 3. The attempt at a solution Not much of an attempt because I'm in doubt at a solution since no equations was given in the lecture slides beyond the standard doppler shift formula of: fd= -fc*2*vr/c Where, fd= doppler shifted frequency of the carrier frequency fc= carrier frequency vr=movement speed of target, probably in km/h I suspect, but not sure if this is in m/s which would make sense I think. c= propagation speed of electromagnetic radiation in vacuum. I'm a bit rusty in this, I knew the answers a few semester ago, but wouldn't hurt getting other eyes on the problem, which is quite simple.
