Israeli companies defeat drones with new technology

August 3, 2017  - By

Drones have become a serious threat, able to penetrate airspace for surveillance or with an explosive payload.

The Islamic State has used weaponized drones against both Syrian and Iraqi forces; groups like Hezbollah and Hamas have sent drones into Israel and are said to be working on upgrading their UAVs for use in both intelligence gathering and offensive operations.

On April 27, Israel used a Patriot missile to take down a drone entering Israeli Airspace from Syria. At $3 million per missile, the Patriot system is an expensive way to down a device that may only be worth $200. Israel has also intercepted drones with fighter jets.

Systems developed by two Israeli companies provide less expensive — and quickly reactive — solutions.

Drone Dome. Rafael Advanced Defense Systems Ltd. has developed a radar and laser-beam system for detecting and destroying drones, with the company adapting its existing laser systems to handle the threat.

Once the system’s radar identifies targets, its laser system destroys them.

Drone Dome also features a jamming system for disrupting communications between the drone and its operator. Drone Dome’s range reaches several miles, but causes minimal interruptions to other systems in nearby urban areas.

The standard Drone Dome system comprises a RADA RPS-42 S-band multi-mission hemispheric radar, a Controp MEOS electro-optical (EO)/infrared surveillance suite, a communications package, and the C-Guard RD jamming and NetSense Wideband detection sensor systems developed by Netline. The UAV threat is neutralized by activation of directional GPS/GNSS and radio-frequency inhibitor/jammer devices.

The RPS-42 is a four-panel tactical air surveillance system delivering 360-degree coverage in azimuth and 90 degrees in elevation, with a detection range of 30 kilometers — including the detection of a minimum target size of 0.002 meters square at a range of 3.2 kilometers — at altitudes from 30 to 30,000 feet. The RPS-42 is designed to detect, track and classify all classes of UAV.

DROM Defense. ORAD’s DROM Drone Defense System can detect an approaching drone at more than 3.5 kilometers away and take command, neutralizing it and landing it far from the operator.

With a weight of 38 kilograms, ORAD’s DROM system comes pre-engineered and pre-assembled. It is mobile and easily deployed on land or at sea in any weather conditions and has an effective coverage range of 3.5 kilometers. It has a 2-kilometer neutralization capability.

Once intercepted, the system can land a hostile a UAV in a pre-defined location, keeping any intelligence it gathered out of enemy hands. It can also identify the location of the operator.

The system’s RF detection unit analyzes signal channels and radio transmissions to spot drones. Once detected, an alarm alerts the system operator.

ORAD has sold the system to clients in several countries including Portugal, Spain and Thailand. The company is in talks with Israeli agencies interested in purchasing the system.
