Which radar indicator is utilized to obtain altitude information?

The RHI scope, or Range Height Indicator scope, is specifically designed to provide altitude information in radar systems. This type of display represents both the range and elevation of targets, allowing operators to visualize how high an object is in the atmosphere relative to their radar location. By presenting data in a three-dimensional format, the RHI scope helps users understand the vertical positioning of targets, which is critical for applications such as air traffic control, weather monitoring, and military operations where altitude is a significant factor.

In contrast, the other options do not serve the same purpose for altitude representation. The azimuth scope primarily displays information based on horizontal positioning and azimuth angles, but lacks the capability to convey height data. The time-delay scope focuses on timing measurements and is not specifically built for altitude tracking. Meanwhile, the binocular scope is an optical device intended for visual augmentation, rather than for processing or displaying radar data. Therefore, the RHI scope stands out as the most relevant choice for obtaining altitude information.
