  2. X band - Wikipedia

    en.wikipedia.org/wiki/X_band

    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 rather indefinitely set at approximately 7.0–11.2 GHz. [citation needed] In radar engineering, the frequency range is specified by the ...

  3. Radar signal characteristics - Wikipedia

    en.wikipedia.org/wiki/Radar_signal_characteristics

    The pulse width ( ) (or pulse duration) of the transmitted signal is the time, typically in microseconds, each pulse lasts. If the pulse is not a perfect square wave, the time is typically measured between the 50% power levels of the rising and falling edges of the pulse. The pulse width must be long enough to ensure that the radar emits ...

    AN/TPY-2 transportable radar. The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array [1][2] X band surveillance radar designed to add a tier to existing missile and air defence systems. It has a range of 2,900 mi (2,500 nmi; 4,700 ...

    en.wikipedia.org/wiki/Pulse-repetition_frequency

    For example, an L band radar system using a PRF of 10 kHz with a duty cycle of 3.3% can identify true range to a distance of 450 km (30 * C / 10,000 km/s). This is the instrumented range . Unambiguous velocity is 1,500 m/s (3,300 mile/hour).

  8. Distance measuring equipment - Wikipedia

    en.wikipedia.org/wiki/Distance_measuring_equipment

    Distance measuring equipment. In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ...

    Azimuth. 360°. Elevation. –10° to +55°. The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.
