What does the vertical coordinate on a B-scope represent?

The vertical coordinate on a B-scope represents range, which indicates the distance of an object from the radar system. The B-scope is a type of radar display that provides two-dimensional information, where the vertical axis is aligned with distance or range and the horizontal axis often represents the azimuth or directional angle. This means that as you read the display, the position of blips or targets on the vertical axis directly correlates to how far away they are from the radar equipment. The B-scope format allows operators to quickly assess the proximity of targets, making range a critical piece of information for radar interpretation.
