What is meant by azimuth resolution?

Azimuth resolution refers to a system's ability to distinguish between two or more targets that are located at the same distance from the sensor but at different angles or bearings. This capability is critical in radar and imaging systems, where it is essential to resolve closely spaced objects in the horizontal plane. High azimuth resolution allows operators to detect and identify distinct targets that may be very close to one another, improving situational awareness and operational effectiveness.

In contrast, options such as the ability to measure distance pertain more to range resolution, while identifying targets at different altitudes focuses on vertical discrimination rather than horizontal separation. The concept of maximum angle of target detection relates to the field of view of a sensor but does not directly address the separation of targets based on direction. Therefore, the understanding of azimuth resolution is fundamentally linked to the separation of targets at the same range on differing bearings, making the selected answer the most accurate reflection of its meaning.
