What is the most common type of antenna position indicating device used in modern RADARs?

🔍 Key Concepts

• How a RADAR display knows the antenna’s exact bearing at every instant • The difference between continuous rotation position sensors and step-by-step positioning devices • Which technology is simple, robust, and traditionally used for antenna bearing transmission on ships

💭 Think About

• Think about which device is designed specifically to transmit angular position information continuously from a rotating element to a display unit • Consider which option is most commonly associated with older and modern marine RADAR scanners for bearing reference, rather than for driving heavy mechanical loads • Ask yourself which device can send accurate angle data over cables without needing complex feedback or control loops

✅ Before You Answer

• Identify which option’s primary purpose is electrical transmission of shaft angle rather than motion control • Eliminate devices that are mainly used as drive/positioning mechanisms instead of angle-reporting sensors • Confirm which technology has historically been standard in marine RADARs for sending the scanner angle to the indicator unit
