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

Resolvers are the most common antenna position indicator in modern radar due to their ability to provide precise, continuous angular feedback in an electrical form compatible with electronic processing; resolvers convert mechanical shaft angle into sine and cosine voltages representing antenna position, offering simplicity, robustness, and ease of integration with modern electronics, surpassing older synchro systems and differentiating from devices used for antenna drive or discrete angular movement.
