Xband frequencies

Type: Concept

As of November 2026, Xband frequencies has been mentioned in one podcast episode on Half as Interesting (Nov 2025). In the episode "The US Military’s Really Big, Really Controversial Radar System" on Half as Interesting, the speaker discusses how SPX1 utilizes Xband frequencies for high-resolution tracking of ICBMs. They explain that higher frequencies lead to higher resolution images, enabling more precise tracking capabilities.

The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) as 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks.
