Active Denial System: Non-Lethal Weaponary

  1. 1. Seminar Guide: Er. Shailendra Gautam Lecturer Electrical Engg. Deptt. Head of Department Dr. Deepak Nagaria Electrical Engg. Deptt. Submitted By: Ujjawal Grover 3rd Year Electrical Engineering Roll Number: 1204320044 A Seminar Topic Presentation on ACTIVE DENIAL SYSTEM (ADS)

  3. 3. Non-Lethal Weapon  Nonlethal weapons are intended to minimize injury or death. While people are occasionally seriously injured or killed by these weapons, fatalities are relatively infrequent.  Nonlethal rounds are firearm rounds which are designed to incapacitate, but not kill, a target. The rounds rely on the transfer of kinetic energy and blunt force trauma to accomplish this incapacitation.  High velocity paintball, Bean Bag Gun, Stun Gun, Laser Gun, Active Denial System, Water Canons, Tear Gas, etc.
  4. 4. Active Denial System  The Active Denial System (ADS) is a nonlethal, directed - energy weapon developed by the U.S. military, designed for area denial, perimeter security and crowd control.  ADS was developed under the sponsorship of the DoD Non- Lethal Weapons Program with the Air Force Research Laboratory as the lead agency.  The ADS was deployed in 2010 with the United States military in the Afghanistan War, but was withdrawn without seeing combat.
  5. 5. History  Two Active Denial Systems were developed under a Defense Department "Advanced Concept Technology Demonstration" Program (now known as Joint Concept Technology Demonstration Program) from 2002 to 2007.  The ADS was deployed in 2010 with the United States military in the Afghanistan War, but was withdrawn without seeing combat.  In 2011, the ADS was redesigned to make it smaller, more reliable, and able to be used on the move. ADS II is being designed to operate from moving aircraft, as well as moving ground vehicles. The redesign does not address problems in different environmental conditions.
  6. 6. Components Of ADS  Electron Gun  Vacuum Chamber  Mirrors (generally concave)  Low light video camera  Thermal imager  Antenna
  7. 7. Principle Of ADS  Dielectric Heating  Dielectric heating, also known as electronic heating, RF heating, high frequency heating is the process in which a high frequency alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material. At higher frequencies, this heating is caused by molecular dipole rotation within the dielectric.  Power generated in skin is given by:
  8. 8. Mechanism of Dielectric Heating  Molecular rotation occurs in materials containing polar molecules having an electrical dipole moment, with the consequence that they will align themselves in an electromagnetic field. If the field is oscillating, as it is in an electromagnetic wave or in a rapidly oscillating electric field, these molecules rotate continuously aligning with it.
  9. 9. Needs of ADS  Two person were killed and nine were injured in police firing during protest in Rohtak, Bihar on July 08, 2014.  For our military, to save more of our troops, and to make them safer.  For our own country, to try to help stop riots and large groups misbehaving
  10. 10. Benefits  Active Denial System is completely non-lethal.  Does not cause long term health problems.  Can be used from long range.  Very mobile.  Handheld version or can be mounted on a hummer.  Very adaptable, can be used anywhere in any conditions, at any time.
  11. 11. Disadvantages  Could be used in inappropriate ways and used as a torture weapon.  When used, could cause people to run away from the ray and trample or stampede others.  If shot into a large group people may not be able to leave, even though they are trying
  12. 12. Conclusion  Non- lethal weaponries especially ADS has proved to be more beneficial in terms of less causalities and collateral damages.  Incapacitation of targets become easy without causing loss of lives.  Indian Government should invest more in non-lethal weaponries rather than lethal ammunitions for dealing with protests and other such matters.
