The main disadvantage of a higher frequency radar is that it __________.

A higher frequency radar operates at shorter wavelengths, which can limit its effectiveness in poor weather conditions. This is primarily due to the increased attenuation that higher frequencies experience when encountering precipitation, fog, or other atmospheric conditions. As the frequency increases, the radar signal is more likely to scatter or be absorbed by moisture in the air, leading to reduced visibility and detection capability in challenging weather scenarios.

In contrast, lower frequency radars can penetrate through such conditions more effectively, allowing for better performance in adverse weather. This characteristic of higher frequency radars makes them less suitable for applications where weather interference is a significant consideration.
