High-Power Compact Microwave Source for Vehicle Immobilization, Final Report
Abstract
Eureka Aerospace has developed a compact single frequency high-power electromagnetic system (HPEMS) for remotely immobilizing vehicles using microwave energy to disable/damage vehicle’s electronic control module/microprocessor which controls engine’s vital functions. The HPEMS consist of rapid charging power supply, capable of delivering of up to 100 pulses per second to the 16-stage Marx generator having erected voltage of 640 kV, whose output consist of 100 Joule, 50 ns long DC pulses. The Marx generator “feeds” the microwave oscillator, consisting of two-transmission line flat-plate Blumlein architecture converting DC pulses into RF-modulated waveform at 350 MHz, using a multiple spark-gap switch configuration. The extension of Blumlein and ground plates into flare horn geometry offers a unique oscillator-high-gain antenna configuration yielding focusing of microwave energy along the focal axis of the antenna. The measured electric field strength at the 30 ft range is approximately 60 kV/m, which corresponds to the power density of 477 W/cm . The limited laboratory test successfully demonstrated the system’s capability of “killing” of the...
