What is a common limitation of Pulse Radar in adverse weather?

The correct response highlights a significant aspect of Pulse Radar technology when it encounters adverse weather conditions. In such scenarios, factors like heavy rain, snow, fog, or thunderstorms can scatter or absorb radar waves, leading to reduced signal clarity and strength. As a result, the radar's ability to accurately measure distance, speed, and other parameters may be notably compromised. This diminished accuracy can affect the radar's performance, making it a critical factor to consider when utilizing pulse radar in less than ideal weather conditions.

The other options suggest limitations that are either overly simplistic or not reflective of the technology's capabilities in these scenarios. For example, the idea that it may only engage minimal signals falls short because Pulse Radar systems can still detect signals in poor weather, just not as accurately. The notion that it cannot function at all is inaccurate since the radar typically can still operate, albeit at reduced effectiveness. Lastly, the assertion that inaccuracies occur only during daylight hours misrepresents how weather impacts radar performance, as adverse conditions can affect readings regardless of the time of day.
