Jam-Duration Optimization for Responsive Vehicle-Protection Jammers

Free registration required

Executive Summary

In this paper, the authors consider responsive communications jamming for vehicle protection against Radio-Controlled Improvised Explosive Devices (RCIEDs). Unlike barrage jamming systems, which operate in an open-loop fashion, responsive jammers scan the radio spectrum on a regular basis and are thus able to react to upcoming signal activities. This allows to focus the available jamming energy on relevant time fractions and frequency bands, which potentially leads to significantly improved jamming efficiencies. In the first part of the paper, they provide a tutorial overview of the various theoretical and practical challenges that are associated with this new jamming technology. In the second part, they turn to the problem of jam-duration optimization for a given set of jammer and RCIED parameters.
