phase difference 2 signals.

is possible whit fpga FFT or similar metod measure a phase difference from 2 PULSED-sinusoidals signals? the freq of signals is 60MHz but the duration of signals is 0.5uSEC, and the PRF of pu...

tnx to all!

i must analize 3 (or 4) PULSED-RADAR-signals. The minimum duration of signals is 0,5 uSEC (typ 1 uSEC). i need to measure the amplitude and and the phase of these signals, referenced at 1 CW (continuos sinusoidal wave) generated by 1 reference-local-oscillator (60 MHz).

In analogic circuit i have not problem, using AD8302(analog devices chip), but i need do it in digital world whit fpga..

tnx!!
