The phenomenon where terrain behind an object masks the radar transmission is represented on the display as what?

Explanation:
The displayed phenomenon is an object masking out a radar transmission. When a terrain feature or near object sits in the radar’s line of sight, it intercepts the beam and prevents energy from reaching or returning from terrain behind it. The display communicates this by showing the near object as the cause of the blocked transmission, i.e., it’s masking the radar signal. This is different from a weather echo (which would appear as a return) or a generic shadow without an indicating object, and it’s not simply no return in the area but the explicit masking action by the object.
