Principle of Operation of FMCWR
- Continuous Transmission: FMCW Radar always sends out a signal that changes its frequency slowly over time. People often get this frequency change using a saw-like or triangle shaped pattern.
- Transmission and Reflection: The sent signal goes through space until it meets a target. When the signal hits its goal, it bounces back towards the radar system.
- Frequency Shift: The signal sent back from the target changes its frequency depending on how far it is and how fast it moves. If the target is moving, changes in sound (beat frequency) between sent and received signals give information about how fast it’s going.
- Range Measurement: The time it takes for a signal to be sent and received helps us know how far away the target is. The longer you wait, the more distance is between the radar and target.
