Target Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Target Velocity - (Measured in Meter per Second) - Target Velocity describes the rate at which target moves toward or away from the radar.
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.
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

Doppler Frequency Shift: 20 Hertz --> 20 Hertz No Conversion Required
Wavelength: 0.58 Meter --> 0.58 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

v_t = (Δf_d*λ)/2 --> (20*0.58)/2

Evaluating ... ...

v_t = 5.8

STEP 3: Convert Result to Output's Unit

5.8 Meter per Second --> No Conversion Required

FINAL ANSWER

5.8 Meter per Second <-- Target Velocity
