What is a characteristic of X band radar?

X band radar is characterized by a short wavelength. This specific radar band operates within the frequency range of 8 to 12 GHz, which translates to wavelengths ranging from approximately 2.5 to 1.0 centimeters. The short wavelength is significant because it allows for better resolution and accuracy in detecting objects, making it suitable for various applications, including speed detection.

The other options relate to radar characteristics but do not accurately describe the X band. While medium frequency might indicate a broader range, X band specifically has higher frequencies than the medium range, which includes longer wavelengths. High amplitude is not a defining characteristic of the X band itself; rather, it depends on the power settings used in the radar system. High visibility range could apply to certain types of radar, but it doesn't specifically define X band radar characteristics, as visibility is influenced by environmental factors rather than just the radar band used.
