HAARP is an extremely low frequency radio wave generator. It stands for High Frequency Active Auroral Research Program. It is a massive antennae array up in Alaska on the Copper River Basin. It's altitude fluctuates between 1000 and 3000 feet above sea level. It is operated by the US military, more specifically the Navy and Air Force. It operates between 2.8 and 10 MHz. It was also voted one of the 10 most under reported news stories of the year by journalists.
HAARP is an HF (High Frequency) generator. It generates frequency's directly above the AM band and below the VHF (Very High Frequency) or TV band. It will zap the Ionosphere which is between 40 and 600 miles above the earth's surface. The ionosphere helps to shield out electromagnetic waves from space that are harmful to life on earth. There are other ionospheric heaters located throughout the world. This specific one differs though from the others in that it concentrates all the energy on one specific spot.
This causes a wide beam to focus in on a small area like when you use a piece of glass to start a fire. The others start as a small beam and grows into a bigger area causing the amount of the beam to hit an area to be weaker than when it starts out. The electromagnetic waves then bounce off the ionosphere and radiate back down on the earth. These waves penetrate down to the bottom of the ocean depths. The HAARP project is expected to generate over 1 billion watts when it is completed. It is capable of delivering one watt per square centimeter which can cause the ionosphere to increase and decrease in altitude.
Weather modification is also theoretically possible with HAARP. It can cause one of earth's major weather modifiers, the jet stream, to change in direction by causing plumes of atmospheric particles.
Another effect is the possibility of raising or lowering large amounts of the earth's atmosphere. This could cause certain areas of the atmosphere to be filled with air or depleted of air. Large amounts of energy could possibly be sent great distances with this technology. Another technological possibility is to spray large area's of the earth with varying wave frequencies and change the frequency. This includes bombarding the frequency of the one that the human brains operate on. You can then cause people to feel a certain way. People can also be disoriented by this procedure.
Many of HAARP's functions are geared to the military. The ability to send electromagnetic waves down to the depth's of the ocean could help to setup a worldwide system of communication with submarines. This would allow submarines to stay at great depths without having to ascend and risk giving away their position when communicating. Another possibility is the defense of a nation's airspace by causing the atmosphere to group up in certain areas and increase the drag for non-guided missiles. This causes their speed to be affected by the friction increase. The missile will then possibly fall short of it's target or run out of fuel. A defense against guided missiles is to bombard it with large amounts of energy of different frequencies. This can cause the missile to become disoriented and can't distinguish between which signal is the correct one. This effect can also be used on air planes. It can cause the instruments and electronics to become corrupted. They also can become overloaded and stop working properly. Brain waves can also be altered and mimicked. This can possibly and theoretically done with HAARP. The operators can cause great amounts of population to be made to think a certain way. This is done by altering the brains wave lengths. As of now you can't put specific thoughts into someone's head. You can only cause people to feel certain feelings such as sadness, happiness or depression. This could be used to control a population by making them feel a certain way anytime a certain thing happens, such as liking a president everytime he makes a speech because you always feel good during and afterwards his speech. This can also be used as crowd control. This is done by making people disoriented. They
