Directed Energy Active Denial System for security applications

On May 19 a memorandum of understanding was completed between DOE-SSA, Sandia, DoD-OFT, and AFRL. This memorandum establishes a formal partnership between the DoD and DOE in developing small-sized ADSs. During the next six months the AFRL’s Human Effectiveness Directorate, Brooks City-Base, is being funded by the OFT to complete human effects testing. This testing will use the SSA ADS system to determine its effectiveness for DOD applications and validate the conclusions of the 2004 small-beam-size effectiveness study sponsored by SSA.

Testing results from Sandia, AFRL, and OFT will guide the operational concept and design of a second-generation small-size ADS system expected to be fielded at several DOE nuclear facilities as early as 2008. DOE-SSA and Sandia will continue to actively seek opportunities to collaborate with other government agencies on technical issues associated with developing and deploying ADS systems.

System uses beam of electromagnetic energy to heat human Active Denial Technology (ADT) provides an effective nonlethal active-response mechanism to disperse, disturb, distract, and establish the intent of intruders.

ADT emits a 95 GHz non-ionizing electromagnetic beam of energy that penetrates approximately 1/64 of an inch into human skin tissue, where nerve receptors are concentrated. Within seconds, the beam will heat the exposed skin tissue to a level where intolerable pain is experienced and natural defense mechanisms take over.

This intense heating sensation stops only if the individual moves out of the beam’s path or the beam is turned off. The sensation caused by the system has been described by test subjects as feeling like touching a hot frying pan or the intense radiant heat from a fire. Burn injury is prevented by limiting the beam’s intensity and duration.

DoD-sponsored millimeter-wave human effectiveness testing, initiated in 2001, has demonstrated ADT as both effective and safe without any long-term effects. It is expected that the DoD-funded human effectiveness testing of the small-beam ADS by the AFRL HEDR during the next six to eight months will validate its effectiveness and safety as a nonlethal weapon system.
