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...

That is a good point. You mean demodulate signal to its two I/Q components and demodulate reference similarly then check phase/amplitude.

It eventually depends on application resolution and noise level. Demodulation may need filtering the sideband.
