5 Questions
What is the direction of transmitter motion that causes an apparent increase in the transmitted frequency?
Towards the receiver and away from the transmitter
What is the principle behind the Doppler Navigation System?
Comparing the frequency of transmitted and received radio signals
When does an apparent decrease in the transmitted frequency occur due to the Doppler effect?
When the transmitter moves away from the receiver
What is the result of the transmitter moving towards the receiver on the transmitted frequency?
An apparent increase in frequency
What is the relationship between the transmitter velocity and the apparent change in frequency?
The apparent change in frequency is directly proportional to the transmitter velocity
Study Notes
Doppler Effect
- An apparent increase in the transmitted frequency occurs when the transmitter moves towards the receiver or the receiver moves towards the transmitter.
- An apparent decrease in the transmitted frequency occurs when the transmitter moves away from the receiver.
Doppler Navigation System
- The Doppler Navigation System is based on the Doppler effect.
Doppler Effect Scenarios
- When the transmitter moves away from the receiver, an apparent decrease in the transmitted frequency occurs, proportional to the transmitter's velocity.
- When the transmitter moves towards the receiver, an apparent increase in the transmitted frequency occurs, proportional to the transmitter's velocity.
- When both the transmitter and receiver move towards each other, an apparent increase in the transmitted frequency occurs, proportional to the transmitter's velocity.
This quiz covers the principles of Doppler effect and its application in navigation systems, including frequency shifts and velocity.
