What is typically the main risk when using RADAR in adverse weather conditions?

In adverse weather conditions, the primary concern when using RADAR is signal distortion. Weather phenomena such as rain, snow, fog, or thunderstorms can scatter and absorb the RADAR signals, leading to degradation in the quality of the data obtained. This distortion impacts the accuracy of distance and speed measurements by causing erroneous readings or interpretation of the detected objects.

While obstructed signals and improper calibration can also affect RADAR performance, they are typically more specific to physical barriers or user errors, rather than a direct result of weather. Overheating is not a common risk associated with RADAR operation in adverse weather and pertains more to mechanical or electronic failure rather than environmental conditions. Therefore, signal distortion remains the most significant risk, as it directly influences the reliability and effectiveness of RADAR systems in challenging weather scenarios.
