Pulse Repetition Frequency Solution

Follow our step by step solution on how to calculate Pulse Repetition Frequency?

FIRST Step Consider the formula

f rep = \frac{[c]}{2 \cdot R un}

Next Step Substitute values of Variables

∴

f rep = \frac{[c]}{2 \cdot 8.79km}

Next Step Substitute values of Constants

∴

f rep = \frac{3E+8m/s}{2 \cdot 8.79km}

Next Step Convert Units

∴

f rep = \frac{3E+8m/s}{2 \cdot 8790m}

Next Step Prepare to Evaluate

∴

f rep = \frac{3E+8}{2 \cdot 8790}

Next Step Evaluate

∴

f rep = 17053.0408418658Hz

LAST Step Rounding Answer

∴

f rep = 17053.0408Hz

Formulas to find Maximum Unambiguous Range

Light speed in vacuum

Light speed in vacuum is a fundamental physical constant representing the speed at which light propagates through a vacuum.

Symbol: [c]

Value: 299792458.0 m/s

Other formulas in Radar and Antenna Specifications category

Go Range of Target

R t = \frac{[c] \cdot T run}{2}

Go Measured Runtime

T run = 2 \cdot \frac{R t}{[c]}

Go Maximum Unambiguous Range

R un = \frac{[c] \cdot T pulse}{2}

Go Pulse Repetition Time

T pulse = \frac{2 \cdot R un}{[c]}

How to Evaluate Pulse Repetition Frequency?

Pulse Repetition Frequency evaluator uses Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range) to evaluate 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 evaluate Pulse Repetition Frequency using this online evaluator? To use this online evaluator for Pulse Repetition Frequency, enter Maximum Unambiguous Range (R_un) and hit the calculate button.

FAQs on Pulse Repetition Frequency

What is the formula to find Pulse Repetition Frequency?

The formula of Pulse Repetition Frequency is expressed as Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range). Here is an example- 170.5304 = [c]/(2*8790).

How to calculate Pulse Repetition Frequency?

With Maximum Unambiguous Range (R_un) we can find Pulse Repetition Frequency using the formula - Pulse Repetition Frequency = [c]/(2*Maximum Unambiguous Range). This formula also uses Light speed in vacuum constant(s).

Can the Pulse Repetition Frequency be negative?

No, the Pulse Repetition Frequency, measured in Frequency cannot be negative.

Which unit is used to measure Pulse Repetition Frequency?

Pulse Repetition Frequency is usually measured using the Hertz[Hz] for Frequency. Petahertz[Hz], Terahertz[Hz], Gigahertz[Hz] are the few other units in which Pulse Repetition Frequency can be measured.
