Design for VHF jammer (134-176 MHZ) against improvised explosive devices

Abstract

Military operation started in FATA areas since 2001 and the Pakistan army was attacked in 2002 for the first time and that too by an IED. Since then Pakistan army has seriously suffered a lot of casualties both in terms of soldiers and equipment. FATA is considered to be the hub of the IEDs (improvised explosive devices) .This type of war in which we use the guerrilla tactics and the IED technique took birth after the Vietnam War. The remotely controlled IED especially used in Afghanistan and Iraq war. There was a study carried out to counter the IED. The idea of developing the jammers was employed to counter IED from 2007 onwards. The American and the European jammers are too costly so there was a need felt to develop a low cost jammer in VHF range. Pakistan is going through severe social and security threat against national prosperity due to terrorist bombings activities. Terrorists often use remote control devices, such as walkie talkie phones that generally operate in the VHF band etc, for activation of remote control devices. The project will give an easy and low cost tool for jamming of VHF band remote control improvised explosives devices in a selective region of the VHF band range because the IEDs can be made in a large variety of shapes and sizes and some time there shape is in such a form that cannot be even expected, they can be on the roadsides, in garbage ,in cars, placed on animals etc.The project will provide the jamming of the IEDs by the best possible approach.VHF jammer between the range (136 to 176MHz )will transmits on the same frequencies as the targeted IEDs are operating on hence disrupting and jamming the communications and blocks the working of the IEDs . The jammer will be able to jam/block the frequencies denying the terrorist to operate RC-IEDs and hence saves the IEDs from detonating and being explode.
