Pulse Repetition Frequency Calculator

meters

This calculator determines the Pulse Repetition Frequency (PRF) and Pulse Repetition Time (PRT) in radar systems based on the maximum unambiguous range. It helps in understanding radar signal timing and avoiding target range ambiguities.

Formulas

PRF (Hz) = c / (2 × Rmax)

PRT (s) = 1 / PRF

where c = 3 × 10⁸ m/s

Formula Explanation

  • PRF defines how often radar pulses are transmitted per second.
  • PRT is the time interval between two consecutive pulses.
  • Rmax is the maximum unambiguous detection range of the radar.

Example

Input: Rmax = 100 km

Result: PRF ≈ 1500 Hz, PRT ≈ 0.00067 s

Who uses it

Useful for radar system designers and engineers optimizing pulse timing and detection range.
