Show the answer
Correct answer: c) To make our vessel more visible on the radar screens of other ships.
Why it is correct
A radar reflector is a device (usually passive, made of mutually perpendicular metal corner plates) that reflects incoming radar pulses back toward the source, strengthening the echo so our small craft shows up clearly on other vessels’ radar screens.
Why the others are not
- a) A standard radar reflector reflects radar energy; it is not a directional radio receiver.
- b) The instrument that measures speed through the water and distance run is the log (corredera).
- d) Its purpose is not filtering electronic interference, but boosting the vessel’s radar echo.
How to work it out in the exam
- Radar reflector: strengthens the radar echo so our craft is more visible on other ships’ radars.
