Israel Aerospace Industries (IAI) has joined the wide effort to bring to the market an effective system that can detect and foil attacks by UAV’s.

The company has unveiled the Drone Guard: a system for drone detection, identification and flight disruption.
The use of small drones has increased dramatically over the years, making them a potential threat to critical infrastructures, other aircrafts and homeland security (HLS), due to their small size, low speed and low flight altitude.

These drones may be used for a number of reasons, including hostile purposes such as intelligence gathering, smuggling, or as weaponized platforms. In addition, they are difficult to detect or disrupt due to their low visibility and low Radar Cross Section (RCS).

To meet this emerging challenge, IAI’s subsidiary ELTA has developed a special system that integrates a 3-Dimensional (3D) radar and Electro-Optical (EO) sensors for detection and identification, as well as dedicated Electronic Attack (EA) jamming systems for disrupting drone flight.

To detect low signature, low-level and low-speed airborne targets, ELTA has adapted to this specific mission its 3D radars, which include the ELM-2026D, ELM-2026B and ELM-2026BF for short (10km), medium (15 km) and long (20 km) ranges, respectively, with special drone detection and tracking algorithms, as well as adapting them with EO sensors for visual identification of the target.

In order to disrupt the hostile UAV, ELTA has developed advanced adaptive jamming systems which can be used in concert with its detection and identification sensors, or as a continuously operated stand-alone system. The jamming disrupts the drone’s flight and can either cause it to return to its point-of-origin (‘Return Home’ function) or to shut down and make a crash landing.

According to IAI, Drone Guard systems have been extensively and successfully tested against a variety of different drones and scenarios, including simultaneous multiple drone penetrations or attacks.
