Mini-drones represent an increasing threat to both public events and military missions. In particular, autonomously-operating mini-drones enhance the new threat from the air.
Countermeasure systems based only on interference with radio signals as well as GPS jamming/spoofing do not provide reliable protection.
By contrast, the HPEM (1) counter-UAS system developed by Diehl Defence acts directly on the control electronics of mini-drones by means of electromagnetic pulses, thus causing mission abort.
This means: regardless of the control method used (autonomous or radio-controlled), the mini-drone becomes inoperable upon impact of HPEM pulses at distances of up to several hundred meters and triggers the fail-safe function.
Diehl's counter-UAS system provides the possibility of scalable range and the ability to also intercept entire swarms of mini-drones simultaneously.
Diehl's HPEM systems which do not cause harm to individuals are already being used for stopping cars and protecting large events (Olympic Games and summit meetings).
