Difference between Directed-energy weapon and Radar

Directed-energy weapon vs. Radar

A directed-energy weapon (DEW) is a ranged weapon system that inflicts damage at a target by emission of highly focused energy, including laser, microwaves and particle beams. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects.

Active electronically scanned array

An active electronically scanned array (AESA), is a type of phased array antenna, that is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

Anti-aircraft warfare

Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action."AAP-6 They include ground-and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures (e.g. barrage balloons).

Arnold Wilkins

Arnold Frederic Wilkins OBE (20 February 1907 – 5 August 1985) was a pioneer in developing the use of radar.

Close-in weapon system

A close-in weapon system (CIWS), is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted shipboard in a naval capacity.

Death ray

The death ray or death beam was a theoretical particle beam or electromagnetic weapon of the 1920s and 1930s that was claimed to have been invented independently by Guglielmo Marconi, Nikola Tesla, Harry Grindell Matthews, Edwin R. Scott, and Graichen, as well as others.

Electronic warfare

Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum or directed energy to control the spectrum, attack of an enemy, or impede enemy assaults via the spectrum.

Hertz

The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Phased array

In antenna theory, a phased array usually means an electronically scanned array; a computer-controlled array of antennas which creates a beam of radio waves which can be electronically steered to point in different directions, without moving the antennas.
