Spatial Resolution

Definition

Spatial resolution refers to the ability of a sensing system to distinguish between two closely spaced objects or features. It plays a crucial role in determining the detail and clarity of the information gathered, especially in imaging and sensing applications, where the precise location of signals is essential for accurate interpretation.
