What is a key disadvantage of Pulse Radar technology?

Pulse Radar technology is designed to emit pulses of radio waves to gather information about the distance and speed of objects. A key disadvantage of this technology is that its performance can be affected by heavy traffic, which can lead to signal interference and cluttered return signals. When multiple objects are moving in close proximity, the radar system may struggle to accurately discern the desired target from other nearby objects. This can result in reduced effectiveness, as the radar reads reflections from multiple sources, making it challenging to isolate specific targets or gauge their speeds and distances reliably.

The other options present various characteristics, but they do not address the core operational challenge of Pulse Radar in congested environments, where overlapping signals can significantly degrade the quality of the information collected.
