Pulse repetition interval

The Pulse Repetition Interval (PRI) is the time the pulse cycle takes before repeating. It is equal to the reciprocal of the PRF or Pulse Repetition Rate (PRR), the number of transmitted pulses per second. PRI is important because it determines the maximum unambiguous range or distance of the radar.

How do you find the pulse repetition interval?

PRT = pulse repetition time. PRT has units of time and is commonly expressed in ms. PRT is the interval between the start of one pulse and the start of another. PRT is also equal to the sum, PRT = PW+RT.

What is the normal range of pulse repetition rates?

What is the normal range of pulse repetition rates? 500 to 2,000 pps. The pulse repetition rate is how many pulses are created in a unit of time.

What does PRF mean in ultrasound?

A change in phase translates to a change in frequency—e.g. when the returning signal is compared to the emitted, returning wave tops will not correspond to the emitted wave tops because the distance between the tops has changed. The number of these pulses per second is called the pulse repetition frequency (PRF).

What is the meaning of PRF?

The pulse repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit. The term is used within a number of technical disciplines, notably radar.
