Target Velocity Solution

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

FIRST Step Consider the formula

v t = \frac{Δf d \cdot λ}{2}

Next Step Substitute values of Variables

∴

v t = \frac{20Hz \cdot 0.58m}{2}

Next Step Prepare to Evaluate

∴

v t = \frac{20 \cdot 0.58}{2}

LAST Step Evaluate

∴

v t = 5.8m/s

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 Target Velocity?

Target Velocity evaluator uses Target Velocity = (Doppler Frequency Shift*Wavelength)/2 to evaluate the Target Velocity, The Target Velocity formula is defined as the velocity of the target that is moving with doppler frequency relative to wave source. Target Velocity is denoted by v_t symbol.

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

FAQs on Target Velocity

What is the formula to find Target Velocity?

The formula of Target Velocity is expressed as Target Velocity = (Doppler Frequency Shift*Wavelength)/2. Here is an example- 5.8 = (20*0.58)/2.

How to calculate Target Velocity?

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

Can the Target Velocity be negative?

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

Which unit is used to measure Target Velocity?

Target 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 Target Velocity can be measured.
