The Sector General books by James White: The 1963 novel Star Surgeon is the source of the combined tractor/pressor beam weapon called the Rattler. The weapon attracts then repels the target (an entire ship or a segment of the ship's hull) at 80 g s, several times a minute.
The adaptive beamforming system dynamically adapts in order to maximize or minimize a desired parameter, such as Signal-to-interference-plus-noise ratio. An antenna gain pattern created by adjusting phase and magnitude of signal transmitted by Tx1, Tx2, and Tx3. Dynamically adjusting phase and magnitude will cause the antenna gain pattern to ...
Linear antenna arrays driven by Butler matrices, or some other beam-forming network, to produce a scanning beam are used in direction finding applications. They are important for military warning systems and target location. [18] They are especially useful in naval systems because of the wide angular coverage that can be obtained. [19]
It consists of multiple dipoles in a two-dimensional array, each fed through an electronic phase shifter, with the phase shifters controlled by a computer control system. The beam can be instantly pointed in any direction over a wide angle in front of the antenna. Used for military radar and jamming systems. Adcock antenna
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
StarFire is a wide-area differential GPS developed by John Deere's NavCom and precision farming groups. StarFire broadcasts additional "correction information" over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is ...

A tractor beam is described as an invisible force field that can grab, trap, suspend, and move objects with force. According to Star Wars sources, tractor beams generators and projectors are common components on many spacecraft, with both military and civilian applications. Tractor beams can be used to move cargo, tow disabled vessels, or ...
