What does azimuth/bearing resolution refer to?

Azimuth or bearing resolution refers to the radar system's ability to distinguish between targets that are located at the same range but on different angles or directions. This capability is crucial for effectively tracking and identifying multiple targets close to one another. When two or more targets are in the same line of sight—meaning they are at the same distance—it is the azimuth resolution that allows the radar to differentiate between these targets based on their bearings, facilitating accurate targeting and tracking in complex environments.

In contrast, other choices focus on different aspects of radar operation. For example, tracking multiple targets at various distances relates to range resolution rather than azimuth resolution. Precision in distance measurements pertains to how accurately the radar can judge the distance to a target. Lastly, the configuration of radar antennas affects their overall performance and coverage but does not specifically describe their ability to resolve bearings or azimuth. Therefore, the ability to distinguish between targets at the same distance on different bearings is a defining characteristic of azimuth resolution.
