What type of radar scope displays a plot of azimuth versus elevation angle?

The type of radar scope that displays a plot of azimuth versus elevation angle is known as the R Scope. This scope is specifically designed to visualize radar data in a way that allows operators to assess both the horizontal (azimuth) and vertical (elevation) positions of targets. This is particularly useful in tracking objects that move in three-dimensional space, providing critical information for radar system operators in various applications such as aviation, maritime navigation, and military operations. The R Scope’s capability to effectively represent these angles makes it a vital tool for understanding the complete spatial orientation of detected objects.

Other radar scope types, such as the C Scope, E Scope, and P Scope, serve distinct purposes primarily focusing on either range or specific signal characteristics but do not provide the comprehensive azimuth-elevation representation inherent to the R Scope. Thus, the R Scope's unique feature of combining both angles positions it as the correct answer.
