Pulse repetition frequency (PRF) indicates the number of ultrasound pulses emitted by the transducer over a designated period of time. It is typically measured as cycles per second or hertz (Hz). In medical ultrasound the typically used range of PRF varies between 1 and 10 kHz 1.

What is meant by pulse repetition frequency?
The waveform of a pulsed radar is usually represented by the pulse duration τ, the pulse repetition interval (PRI) T, or the pulse repetition frequency (PRF) fp. PRI is the time interval between two adjacent pulses. PRF is the rate that pulses repeat per second and is equal to the inverse of PRI.
How do you calculate pulse repetition frequency?
PRT is also equal to the sum, PRT = PW+RT. PRF = pulse repetition frequency. PRF has units of time-1 and is commonly expressed in Hz (1 Hz = 1/s) or as pulses per second (pps). PRF is the number of pulses transmitted per second and is equal to the inverse of PRT.
What should be the pulse repetition frequency of a radar?
3.2 Pulse Repetition Frequency. PRF is normally expressed as the number of pulses transmitted in 1 s and is therefore denoted in Hertz or pps (pulses per second). Typical values for a marine radar are 1000–3000 pps.
