Next Step for Drones: Defending Against Them

Antidrone defense systems are a rising new business as military, aviation concerns mount.

The battle of Captieux lasted just a few seconds, and ended in a decisive defeat for the would-be invader.

The enemy drone, flying at a French military installation south of Bordeaux, was easily spotted on radar, an integrated video camera confirmed its identity, and a quick burst from a radio-frequency jammer disrupted its communication signals, diverting the drone from its target.

It was the first time a group of small British companies had demonstrated their antidrone defense system on an international stage, said Mark Radford, chief executive of Blighter Surveillance Systems, maker of the system’s radar.

As Amazon Inc. and Google Inc. consider drones for tasks ranging from package delivery to providing high-speed Internet, regulators and military planners worry that low-cost drones, which are widely available for purchase, could pose a threat to commercial aviation, vital infrastructure and even troops.
