A three year research program is proposed to establish an array of wideband ELF/VLF receivers and to conduct continuous measurements of the magnetospheric response to the injection of ELF/VLF waves using the HAARP HF heater. The primary objective of the proposed program is to detect the so-called ‘one-hop’ direct and the ‘two-hop’ whistler-mode echo of a HAARP-injected ELF/VLF signal, and to study the characteristics of these signals to determine the degree to which injected ELF/VLF signals are amplified by the magnetospheric plasma, leading to the triggering of new emissions and enhanced precipitation of energetic electrons from the radiation belts. The scientific opportunities, background and justification for ELF/VLF wave-injection and magnetospheric probing experiments with HAARP are provided in Attachment A, which is a copy of a detailed report prepared earlier (April 2001) by Stanford for preliminary ELF/VLF wave-injection campaigns conducted under the auspices of the Polar Aeronomy and Radio Science (PARS) program.
High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments
Electromagnetic Pulse (EMP) is an instantaneous, intense energy field that can overload or disrupt at a distance numerous electrical systems and high technology microcircuits, which are especially sensitive to power surges. A large scale EMP effect can be produced by a single nuclear explosion detonated high in the atmosphere. This method is referred to as High-Altitude EMP (HEMP). A similar, smaller-scale EMP effect can be created using non-nuclear devices with powerful batteries or reactive chemicals. This method is called High Power Microwave (HPM). Several nations, including reported sponsors of terrorism, may currently have a capability to use EMP as a weapon for cyber warfare or cyber terrorism to disrupt communications and other parts of the U.S. critical infrastructure. Also, some equipment and weapons used by the U.S. military may be vulnerable to the effects of EMP.
