Characterization, Modeling, and Statistical Analysis of the Electromagnetic Response of Inert Improvised Explosive Devices

The experimental characterization of the electromagnetic (EM) response of a set of inert improvised explosive devices (IEDs) is presented in this paper. The characterization is based on measurements of gain and input impedance of the firing circuits of inert IEDs in the range of 200 MHz to 2 GHz. First, a theoretical model to predict the average gain is developed. A comparison between the measurement results and theoretical predictions is presented. Then, the power delivered to a hot wire-based electro-explosive device connected to the inert IED is calculated for each measured case and it is statistically analyzed. The effects on the IED response of different characteristics of the coupling, such as the IED's elements, the incident field polarization, and the impedance mismatch, are also studied. In addition, the statistical performance of the induced power and current are determined and compared with the results of a numerical model based on Monte Carlo simulations. It is demonstrated that both approaches, a theoretical model based on an equivalent antenna and Monte Carlo simulations, can be used to describe the average EM response of the firing circuit of IEDs.

Circular polarization

In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave. In electrodynamics, the strength and direction of an electric field is defined by its electric field vector. In the case of a circularly polarized wave, the tip of the electric field vector, at a given point in space, relates to the phase of the light as it travels through time and space.

Polarization (physics)

Polarization (also polarisation) is a property of transverse waves which specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string (see image); for example, in a musical instrument like a guitar string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string.

Bomb

A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia.

A Computational Framework For Two-Dimensional Random Walks With Restarts
