Radial Velocity Solution

Follow our step by step solution on how to calculate Radial Velocity?

FIRST Step Consider the formula

v r = \frac{f d \cdot λ}{2}

Next Step Substitute values of Variables

∴

v r = \frac{10.3Hz \cdot 0.58m}{2}

Next Step Prepare to Evaluate

∴

v r = \frac{10.3 \cdot 0.58}{2}

LAST Step Evaluate

∴

v r = 2.987m/s

Radial Velocity Formula Elements

Variables

Radial Velocity

The Radial Velocity of an object with respect to a given point is the rate of change of the distance between the object and the point.

Symbol: v_r

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

Formulas to find Radial Velocity

Doppler Frequency

Doppler frequency refers to the frequency shift that occurs in a wave, such as sound waves, light waves, due to the relative motion between the source of the wave and the observer.

Symbol: f_d

Measurement: FrequencyUnit: Hz

Note: Value should be greater than 0.

Formulas to find Doppler Frequency

Wavelength

Wavelength refers to the physical length of one complete cycle of an electromagnetic wave transmitted by the radar system.

Symbol: λ

Measurement: LengthUnit: m

Note: Value should be greater than 0.

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 Radial Velocity?

Radial Velocity evaluator uses Radial Velocity = (Doppler Frequency*Wavelength)/2 to evaluate the Radial Velocity, The Radial Velocity formula is defined with respect to a given point is the rate of change of the distance between the object and the point. Radial Velocity is denoted by v_r symbol.

How to evaluate Radial Velocity using this online evaluator? To use this online evaluator for Radial Velocity, enter Doppler Frequency (f_d) & Wavelength (λ) and hit the calculate button.

FAQs on Radial Velocity

What is the formula to find Radial Velocity?

The formula of Radial Velocity is expressed as Radial Velocity = (Doppler Frequency*Wavelength)/2. Here is an example- 2.987 = (10.3*0.58)/2.

How to calculate Radial Velocity?

With Doppler Frequency (f_d) & Wavelength (λ) we can find Radial Velocity using the formula - Radial Velocity = (Doppler Frequency*Wavelength)/2.

Can the Radial Velocity be negative?

No, the Radial Velocity, measured in Speed cannot be negative.

Which unit is used to measure Radial Velocity?

Radial Velocity is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Radial Velocity can be measured.
