Enter the propagation velocity (m/s) and the pulse spacing (m) into the Calculator. The calculator will evaluate the Pulse Repetition Frequency. 

Pulse Repetition Frequency Formula



  • PRF is the Pulse Repetition Frequency (1/s)
  • PV is the propagation velocity (m/s)
  • PS is the pulse spacing (m)

To calculate Pulse Repetition Frequency, divide the propagation velocity by the pulse spacing.

How to Calculate Pulse Repetition Frequency?

The following steps outline how to calculate the Pulse Repetition Frequency.

  1. First, determine the propagation velocity (m/s). 
  2. Next, determine the pulse spacing (m). 
  3. Next, gather the formula from above = PRF = PV / PS.
  4. Finally, calculate the Pulse Repetition Frequency.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

propagation velocity (m/s) = 478

pulse spacing (m) = 2
