The pulse repetition interval (PRI) is the time interval between pulses. It should be noted that PRF and PRI effectively refer to the same feature and are simply related by the expression PRF=1/PRI.

What is high pulse repetition frequency?

A high pulse repetition frequency pulse doppler radar in which the prf is large enough to have no blind speeds [as given by Eq. (32)] within the expected values of target doppler frequencies.

What is importance of PRF?

PRF can be used to promote wound healing, bone regeneration, graft stabilization, wound sealing, and hemostasis. Because the fibrin matrix is better organized, it is able to more efficiently direct stem cell migration and the healing program.
