What is primarily used to describe the ability of RADAR to differentiate between multiple targets?

The ability of RADAR to differentiate between multiple targets is predominantly described by the term "Resolution." In the context of radar systems, resolution refers to the minimum separation required between two targets for the radar to distinguish them as separate entities. This can be influenced by various factors, including the type of radar system and the frequency of operation.

Resolution can be categorized into range resolution and angle resolution. Range resolution determines how well the radar can differentiate targets that are located at different distances from the radar, while angle resolution pertains to the ability to distinguish targets that are at the same range but displaced at different angles. Higher resolution allows RADAR systems to detect and track multiple objects more effectively, reducing ambiguity and improving the accuracy of the data obtained.

Other terms such as clarity, accuracy, and precision play different roles in measurement contexts but do not specifically encapsulate the concept of distinguishing between targets as effectively as resolution does. Clarity is more subjective and relates to the overall quality of the returned signal, while accuracy and precision refer to the correctness and consistency of measurements, respectively, rather than the ability to differentiate targets.
