ACTIVE DENIAL SYSTEM
[attachment=65881]
Active Denial System
The Active Denial System (ADS) developed by Raytheon for the US Air Force Research Labs is a non lethal, counter-personnel directed energy non-lethal weapon. it is a strong millimeter-wave transmitter which can be used against human targets at distances beyond the effective range of small arms.
ADS projects a focused millimeter wave energy beam which induces intolerable heating sensation on an adversary's skin and cause that individual to be repelled without injury. ADS could be used to stop, deter and repel hostile elements without applying of lethal force
Directed-energy weapon
A directed-energy weapon is a type of energy weapon that directs energy in a particular direction by a means other than a projectile. It transfers energy to a target for a desired effect. Some of these weapons are real or practicable; some are science fiction. The energy is in various forms:
Electromagnetic radiation (typically lasers ).
Particles with mass (particle beam weapons).
Fictional weapons often use some sort of radiation or energetic particle that does not exist in the real world.
CONSTRUCTION OF ADS
An ADT system consists of an electrical power source, a device producing a beam of millimeter-wave energy, an antenna directing energy towards a target, and a beam transport connecting the source and antenna.
Operations
The ADS works by directing electromagnetic radiation at a frequency of 95 GHz[3] toward the subjects.
The waves excite (see Excited state) water molecules in the epidermis (skin) to around 55C ,causing an intensely painful burning sensation.
There is no indication on the feasibility of electromagnetically shielding a person from its effects with a wire mesh.
A higher radio frequency is chosen because, as a property of electromagnetic waves (known as "skin depth"), they are unable to penetrate the body as deeply as lower frequency waves, thereby affecting external organs only, such as skin.
Electromagnetic shielding
Electromagnetic shielding is the process of limiting the flow of electromagnetic fields between two locations, by separating them with a barrier made of conductive material. Typically it is applied to enclosures, separating electrical devices from the 'outside world', and to cables, separating wires from the environment the cable runs through. Electromagnetic shielding used to block radiofrequency electromagnetic radiation is also known as RF shielding.
The shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields, though not static or low-frequency magnetic fields. (A conductive enclosure used to block electrostatic fields is also known as a Faraday cage.) The amount of reduction depends very much upon the material used, its thickness, and the frequency of the fields of interest
CONCLUSION
In the final analysis, ADT is meant to save lives. Active denial is a revolutionary force protection technology that will help fill the non-lethal capability gap. ADT systems will provide field commanders with a non-lethal force option in situations where the use of lethal force is authorized, but not preferred.
One of the attractive features of ADT is that the probability of hit is 100% since ballistics effects are irrelevant. The energy beam travels at the speed of light. As long as electricity is available, a continuous or pulsed beam of energy can be projected. Operators can direct this beam toward individual targets, sweep it across many targets, dwell it to suppress snipers, or create an energy barrier. The range of ADT considerably exceeds the range of conventional non-lethal technologies and is meant to outrange small arms fire. Possible applications of ADT are airborne, maritime, fixed site, or man-portable. Researchers are studying all applications for their operational benefits and technical feasibility.
