The X-band is a segment of the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of X-band is rather indefinitely set at approximately 7.0 to 11.2 gigahertz (GHz). In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (I.E.E.E.) at 8.0 to 12.0 GHz.
The term "X-band" is also used informally and inaccurately to refer to the extended AM broadcast band, where the "X" stands for "extended".
Wiki: X Band
X-Radar is probably referring to the use of X-band for radar, Here's what wikipedia says about it.
X-band is used in radar applications including continuous-wave, pulsed, single-polarization, dual-polarization, synthetic aperture radar, and phased arrays. 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.[1] X-band is often used in modern radars. The shorter wavelengths of the X-band allow for higher resolution imagery from high-resolution imaging radars for target identification and discrimination.
Hope this explains X band/radar for you.
