PulseRepetitionFrequencyCalculator

This calculator determines the Pulse Repetition Frequency (PRF) of a radar or similar system based on the time interval between pulses.

Calculation Formula

PRF = 1 / τ

Where:
PRF = Pulse Repetition Frequency (pulses per second)
τ = Pulse Interval (seconds)

What is Pulse Repetition Frequency (PRF)?

Pulse Repetition Frequency (PRF) is the number of pulses emitted by a radar system per second. It's a critical parameter that determines the system's capabilities, including range resolution and maximum unambiguous range.

How to Use This Calculator

  1. Enter the pulse interval in seconds. This is the time between consecutive pulses.
  2. Click the Calculate button to compute the PRF.
  3. The calculator will display the PRF in both standard notation and hertz (Hz).

Example Calculation

If a radar system pulses every 1 millisecond (0.001 seconds), the PRF would be:

PRF = 1 / 0.001 = 1000 pulses per second (1 kHz)

Important Considerations

  • The pulse interval must be expressed in seconds for accurate calculations.
  • PRF is inversely proportional to pulse interval - as the interval decreases, the PRF increases.
  • For radar systems, the choice of PRF affects range ambiguity and resolution trade-offs.
