Pulse Repetition Frequency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range)
f_rep = [c]/(2*R_un)
This formula uses 1 Constants, 2 Variables

Constants Used

[c] - Light speed in vacuum Value Taken As 299792458.0

Variables Used

Pulse Repetition Frequency - (Measured in Hertz) - Pulse Repetition Frequency refers to the number of pulses transmitted by the radar system in one second.
Maximum Unambiguous Range - (Measured in Meter) - Maximum Unambiguous Range is the range beyond which the target appears as second-time-around-echoes is the maximum unambiguous range.

STEP 1: Convert Input(s) to Base Unit

Maximum Unambiguous Range: 8.79 Kilometer --> 8790 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_rep = [c]/(2*R_un) --> [c]/(2*8790)

Evaluating ... ...

f_rep = 17053.0408418658

STEP 3: Convert Result to Output's Unit

17053.0408418658 Hertz --> No Conversion Required

FINAL ANSWER

17053.0408418658 ≈ 17053.04 Hertz <-- Pulse Repetition Frequency

(Calculation completed in 00.020 seconds)

Maximum Unambiguous Range

Go Maximum Unambiguous Range = ([c]*Pulse Repetition Time)/2

Pulse Repetition Time

Go Pulse Repetition Time = (2*Maximum Unambiguous Range)/[c]

Range of Target

Go Target Range = ([c]*Measured Runtime)/2

Measured Runtime

Go Measured Runtime = 2*Target Range/[c]

Pulse Repetition Frequency Formula

Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range)
f_rep = [c]/(2*R_un)

What is PRT and PRF?

PRF stands for Pulse Repetition Frequency. It is equal to number of pulses which are transmitted per second. PRT stands for Pulse Repetition Time. The time between beginning of one pulse and start of next pulse is known as Pulse Repetition Time. The PRF and PRT are related as per following equation

How to Calculate Pulse Repetition Frequency?

Pulse Repetition Frequency calculator uses Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range) to calculate the Pulse Repetition Frequency, The Pulse Repetition Frequency formula is defined as the frequency by which pulse has to be released to reach its target. Pulse Repetition Frequency is denoted by f_rep symbol.

How to calculate Pulse Repetition Frequency using this online calculator? To use this online calculator for Pulse Repetition Frequency, enter Maximum Unambiguous Range (R_un) and hit the calculate button. Here is how the Pulse Repetition Frequency calculation can be explained with given input values -> 170.5304 = [c]/(2*8790).

FAQ

What is Pulse Repetition Frequency?

The Pulse Repetition Frequency formula is defined as the frequency by which pulse has to be released to reach its target and is represented as f_rep = [c]/(2*R_un) or Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range). Maximum Unambiguous Range is the range beyond which the target appears as second-time-around-echoes is the maximum unambiguous range.

How to calculate Pulse Repetition Frequency?

The Pulse Repetition Frequency formula is defined as the frequency by which pulse has to be released to reach its target is calculated using Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range). To calculate Pulse Repetition Frequency, you need Maximum Unambiguous Range (R_un). With our tool, you need to enter the respective value for Maximum Unambiguous Range and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
