The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

The AN/APG-81 is an active electronically scanned array (AESA) fire-control radar system designed by Northrop Grumman Electronic Systems (formerly Westinghouse Electronic Systems) for the Lockheed Martin F-35 Lightning II.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic waves in each of these bands have different characteristics, such as how they are ...
The LRTR series of radars has been succeeded by the VLRTR. The VLRTR, or Very Long Range Tracking Radar, has a range exceeding 3,000 km. The GaN-based TRMs may be used by Very Long Range Tracking Radar. To support ballistic missile defence, the Missile Monitoring System uses VLRTR to identify space-borne threats.

Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-7 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
A new generation of thrash metal bands emerged in the early 2000s, drawing lyrical and visual inspiration from the older groups. [10] [11] Thrash metal was an inspiration for later extreme genres such as death metal and black metal. This list also includes certain bands which belong to the first wave of black metal.
