Which term describes the capability of a radar system to distinguish between two closely spaced targets?

The term that captures the ability of a radar system to differentiate between two closely spaced targets is "Range Resolution." Range resolution refers to the radar's ability to separate two targets that are located at nearly the same distance from the radar source. This capability is dependent on several factors, including the radar's pulse width and the frequency of the signals used. Shorter pulse widths and higher frequency signals can improve range resolution, allowing for more precise targeting and improved situational awareness.

In contrast, range accuracy pertains to how precisely the radar can measure the distance to a target, but does not specifically address the ability to differentiate between closely spaced targets. Maximum detection range refers to the furthest distance at which the radar can effectively detect targets, while signal clarity relates to the quality and intelligibility of the radar returns. Understanding these distinctions is crucial for effectively utilizing radar systems in various operational scenarios.
