The Active Denial System (ADS) is a non-lethal directed-energy weapon developed by the U.S. military, [2] designed for area denial, perimeter security and crowd control. [3] Informally, the weapon is also called the heat ray [ 4 ] since it works by heating the surface of targets, such as the skin of targeted human beings.
In 2013, Raytheon demonstrated a ground-based air defense high-powered microwave system derived from CHAMP technology, disabling electronics on small UAVs. The demonstrator resembles the active denial system non-lethal crowd control device, including its reflector and steering mirror. It is integrated with radar automated tracking.
Active Denial System is a millimeter wave source that heats the water in a human target's skin and thus causes incapacitating pain. It was developed by the U.S. Air Force Research Laboratory and Raytheon for riot-control duty. Though intended to cause severe pain while leaving no lasting damage, concern has been voiced as to whether the system ...
Other area denial systems include cruise missiles, long-range strike aircraft, mines, and coastal defense artillery. [3] The term A2/AD was created in 2003 to describe the threats posed by long-range missile systems, precision munitions, and satellite technology that will make military operations in the littoral areas challenging for modern ...
In 2001, the United States Marine Corps revealed its development of a less-than-lethal energy weapon called the Active Denial System, a focused high frequency microwave device said to be capable of heating all living matter in the target area rapidly and continuously for the duration of the beam, causing transient intolerable pain but no ...
[58] [59] In September 2020, it was revealed that federal officials had explored the use of the device and the Active Denial System ("heat ray") to disperse civilians protesting outside the White House in June of that year, but had been advised that the National Guard was not currently in possession of either device. [60]
The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
