Bofors HPM blackout - a versatile and mobile L-band high power microwave system

The BAE Systems Bofors new mobile High Power Microwave system, Bofors HPM Blackout, has proven itself very suitable for research and evaluation of microwave effects in the L-band. The system is composed of an integrated pulsed power unit, a microwave source and an exchangeable conical horn antenna. Adjoining support systems are a compact battery powered vacuum system for the microwave tube and a gas supply system for the pulsed power unit. The integrated battery supply makes the system operational in all terrains and independent of standard laboratory utilities. The total weight of the system is less than 500 kg and the length is just above two meters. The system is capable of generating GW-levels of microwaves and with minor modifications the frequency could be changed well into the S-band without too much loss in power. A typical antenna gain for the system is 15-25 dBi.
