What is the term used to describe the ability of a radar system to separate objects at the same range but at different bearings?

The term that describes the ability of a radar system to separate objects at the same range but at different bearings is azimuth resolution. This aspect of radar performance is crucial because it determines how well the radar can distinguish between two targets that are located at the same distance but are on different angles relative to the radar's position.

Azimuth resolution is influenced by the width of the radar beam and the design of the radar system, including factors such as antenna size and the frequency being used. A radar with good azimuth resolution can accurately detect and differentiate between multiple objects within the same range, allowing for effective tracking and targeting in various applications.

In contrast, range resolution pertains to a radar's ability to differentiate objects that are at different distances, elevation accuracy deals with how accurately a radar can measure height differences, and signal clarity refers more broadly to the quality and intelligibility of the radar signal rather than its ability to separate targets based on their bearings.
