Radar surface-angular measurements are measured in which plane?

Radar surface-angular measurements are specifically measured in the horizontal plane. This is because radar systems assess the angular relationships between the surface of the Earth and the radar's line of sight. The horizontal plane provides a reference for measuring angles in such systems, allowing technicians to determine the precise direction and position of targets on the surface relative to the radar installation.

In radar technology, the horizontal plane is essential for accurately tracking and analyzing targets, such as aircraft or ships, as it aligns with the earth's curvature and maintains consistency in measurement. Other planes, such as vertical, diagonal, or inclined, do not effectively represent surface measurements in the context of radar systems, as they would introduce complexities that could lead to inaccuracies in target acquisition and tracking.
