Which statement is true about RADAR detection in adverse weather conditions?

In adverse weather conditions, such as rain, fog, or snow, the performance and accuracy of RADAR systems can be impacted. Therefore, saying that it may require adjustments to settings is true. Settings might need to be modified to optimize detection and reduce interference from the environmental factors that could otherwise obscure or distort the RADAR signals.

For example, increasing the sensitivity of the RADAR can help in detecting objects that might be masked by heavy rain, while adjusting the display settings can improve the visibility of the data being presented. Being aware of these adjustments is essential for maintaining effective RADAR operation under challenging weather conditions, ensuring accurate readings and reliable law enforcement or traffic management.

The other options imply various levels of effectiveness or necessity for RADAR in adverse conditions that are not accurate, as RADAR can still be used effectively with the right adjustments.
