[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.

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 ...
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.
With Raytheon the U.S. Air Force has developed a nonlethal antipersonnel weapon system called Active Denial System (ADS) which emits a beam of millimeter radio waves with a wavelength of 3 mm (frequency of 95 GHz). [13] The weapon causes a person in the beam to feel an intense burning pain, as if their skin is going to catch fire.

Active Denial System (mounted on an HMMWV) Ground mobility vehicle (GMV) — USSOCOM Special Ops variants — initially based on the M1025; later GMV models based on the M1113 chassis. Another model, based on the M1165 HMMWV can be fitted with armor kits to create an 'up-armored' GMV with additional armor plating and an optional ballistic ...
