Im stuck on this one. I hope someone helps me!
Problem: I need to find Dopler shift with array of reflected chirps.
I have bursts of chirps which then i sampled, and calculated fft. Im suposed to calculate Doppler shift using just spectrum. I see it's shifted but have no idea how to calculate the shift. I tried with boxcars in hope it will be easier and i will notice something, but it's the same thing. Also i find some really useful article and also stuck understanding it.
"Unless the target is moving at an extremely high speed relative to the speed of light, the Doppler shift will be small and very difficult to detect from one pulse. The solution to this problem is to transmit a burst waveform containing repeated pulses. Initially, for simplicity, boxcars were used as the pulse so that some insight into how the parameters of the pulse affect the Doppler shift might be gained." source
