What is the advantage of X band?

The main advantages include providing greater spectral efficiency, lower chance for interference, and less rain fade and greater satellite separation .

X-band is widely used because of the ability to utilize smaller antennas that fit on most boats and to provide better target resolution . S-band radars are often used for specialized applications, such as seeing through heavy weather or precipitation and for long-range bird detection. S-band antennas are larger.

X band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement . X band is often used in modern radars.
