The rifle, called the DroneDefender, uses a radio pulse to disable a
targeted drone within 400 meters. The gun causes the drone to think
it's out of range and enter emergency protocol, either causing it to
land, hover or return to its point of origin.
Because the DroneDefender jams communications between the drone and
the operator, it can also prevent any onboard self destruct mechanisms
from going off.
Battelle Innovations, the company responsible for producing the rifle,
says that it is "a lightweight easy-to-use non-kinetic solution to
defend airspace against UAS without compromising safety or risking
collateral damage." Because no bullets are being fired, there is little
chance something or someone else will get hurt.
