Re: Estimate chirp shift Doppler

Sorry if my question my sound naive ...

If your chirp starts at Fo and Fn, and your measured signal starts at
F1 and ends at Fm
can't you take the spectral shift as the average difference between
these two frequencies (ie, the edge frequencies)?

Hello,
I have a question for you. I have to simulate the
signal received in a radar system by applying a time delay and a
doppler shift. By now I have delayed the original signal and I have
estimated the delay by correlating the original transmitted signal
with the received one and by picking the max. Now I have to estimate
the shift in frequency but I don't know how to proceed. I think I
should multiply the delayed signal for exp(-j*2pi*fd*t) but how can I
estimate the shift? The transmitted signal is a chirp, duration of 100
microsec sampled at 0.5 MHz (50 samples)
Thanks in advance!
