Question
Download Solution PDFA stationary CW radar operating at 5 GHz. What is the Doppler frequency shift, if the target is moving at 108 km/hr speed?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFDoppler Effect:
The Doppler Effect is the change in the observed frequency of a wave when the source or the detector moves relative to the transmitting medium.
The following equation can be used to calculate the Doppler frequency shift (D):
Calculation:
Given:
v = 108 km/hr = 30 m/sec
fcarrier = 5 GHz = 5 × 109 Hz
Also, c = 3 × 108 m/s
The Doppler frequency shift will be:
D = 1000 Hz
