X-band radars operate at much higher frequencies than traditional S-band radars, allowing for improved resolution and accuracy. This makes them particularly useful for detecting and tracking small, fast-moving objects, such as aircraft and missiles. Additionally, X-band radars have a narrower beamwidth, which enables them to focus energy more precisely and achieve greater discrimination between targets.
Secure communications systems operating in the X band can benefit from increased data rates and higher levels of security compared to lower-frequency microwave bands.
