Which parameters are most likely shown on all radar displays?

Range is a fundamental parameter displayed on all radar systems. It refers to the distance between the radar and the object being tracked or detected. This information is crucial as it helps operators determine how far away an object is, which is essential for situational awareness in various applications such as aviation, marine navigation, and weather monitoring.

Other parameters, while important in specific contexts, may not be consistently shown across all radar displays. Elevation and azimuth are relevant for tracking the position of objects in three-dimensional space but are not universally displayed. Speed and direction can vary depending on the radar capabilities and its intended use. Power output levels are typically more relevant during maintenance or calibration of radar systems rather than in operational displays where immediate situational awareness is needed. Thus, range is the key parameter that is universally shown across different types of radar displays.
