What is not considered a limitation on radar operation?

Radar is primarily designed to operate in two dimensions, which means it can provide information about the range (distance) and bearing (direction) of an object but does not directly give altitude or elevation data. This is a fundamental characteristic of how radar technology functions, making the statement that radar can operate in three dimensions inaccurate.

In contrast, the other statements reflect genuine limitations encountered in radar operation. Obstructed views can lead to inaccuracies when the radar signal is blocked or deflected, resulting in a failure to detect objects that would otherwise be visible. Similarly, certain weather conditions, such as heavy rain, fog, or snow, can interfere with radar signals, affecting their effectiveness and reliability. Understanding these distinctions clarifies why the idea of radar operating in three dimensions is not applicable within the constraints of the technology.
