As attack drones multiply, Israeli firms develop defenses

Over a dozen Israeli firms presented cutting-edge anti-drone technologies at London’s DSEI exhibition this month, from defense heavyweights Elbit Systems, Raphael and Israel Aerospace Industries, to smaller start-ups like Vorpal. They are part of a booming global industry with competitors from the U.S., Europe, Singapore, and China.
Anti-drone defenses fall into several categories. Detection systems usually rely on either radio or optical technology to spot incoming drones.
Other systems can stop the aircraft with jammers that down aircraft by scrambling communications, kinetic systems that try to knock the craft out of the sky or systems that allow authorities to seize control of an aircraft.
But for now, none of these systems can provide full protection.
“It’s a nasty target. It’s a problem,” said Turniansky. “It’s going to be cat and mouse for a while.”

Kinetic system are needed, system that shoot buckshot work best.  Also, one needs to keep a surveillance drone in the sky.
