Doppler Frequency Shift Solution

STEP 0: Pre-Calculation Summary

Formula Used

Doppler Frequency Shift = (2*Target Velocity)/Wavelength
Δf_d = (2*v_t)/λ
This formula uses 3 Variables

Variables Used

Doppler Frequency Shift - (Measured in Hertz) - Doppler frequency shift is the change in frequency of a wave in relation to an observer who is moving relative to the wave source.
Target Velocity - (Measured in Meter per Second) - Target Velocity describes the rate at which target moves toward or away from the radar.
Wavelength - (Measured in Meter) - Wavelength refers to the physical length of one complete cycle of an electromagnetic wave transmitted by the radar system.

STEP 1: Convert Input(s) to Base Unit

Target Velocity: 5.8 Meter per Second --> 5.8 Meter per Second No Conversion Required
Wavelength: 0.58 Meter --> 0.58 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δf_d = (2*v_t)/λ --> (2*5.8)/0.58

Evaluating ... ...

Δf_d = 20

STEP 3: Convert Result to Output's Unit

20 Hertz --> No Conversion Required

FINAL ANSWER

20 Hertz <-- Doppler Frequency Shift

(Calculation completed in 00.004 seconds)

What is target velocity?

When the axis is in Closed Loop control, the Target Velocity refers to the speed and direction of a detected object relative to the radar system. The radar system can only determine the component of the target's velocity along the radar's line of sight (radial velocity).

How to Calculate Doppler Frequency Shift?

Doppler Frequency Shift calculator uses Doppler Frequency Shift = (2*Target Velocity)/Wavelength to calculate the Doppler Frequency Shift, The Doppler Frequency Shift formula is defined as the change in frequency of a wave in relation to an observer who is moving relative to the wave source. Doppler Frequency Shift is denoted by Δf_d symbol.

How to calculate Doppler Frequency Shift using this online calculator? To use this online calculator for Doppler Frequency Shift, enter Target Velocity (v_t) & Wavelength (λ) and hit the calculate button. Here is how the Doppler Frequency Shift calculation can be explained with given input values -> 20 = (2*5.8)/0.58.

FAQ

What is Doppler Frequency Shift?
