Question
Which of the following methods is used to locate sources of noise interference or jamming?
Answer Options
- A) Echolocation
- B) Doppler radar
- C) Radio direction finding
- D) Phase locking
Correct Answer: C
Explanation
Locating an unknown, unwanted source of radio noise or illegal jamming is accomplished through the specialized technique of Radio Direction Finding (RDF), often informally called ‘fox hunting’ or ‘T-hunting.’
RDF uses specialized directional antennas (T9A01) and equipment to determine the direction (bearing) from which a signal is originating. By taking multiple bearings from different locations, the source’s position can be triangulated, allowing the operator to pinpoint the source of the interference.
