Israel Aerospace Industries (IAI) has developed a ‘next-generation’ version of its Drone Guard ground-based range of systems for detecting, tracking, and disrupting unmanned aerial vehicles (UAVs).
The enhanced system, announced by the company on 21 November, has been developed by IAI’s ELTA Systems subsidiary and adds communication intelligence (COMINT) for more precise detection, classification, and identification based on broadcast frequencies. Further to the addition of COMINT, the Drone Guard’s 3D radars, electro-optical (EO) and jammer systems have all been upgraded.
“The [COMINT] system can effectively jam or disrupt the drone’s control channel and navigation by supporting an array of communication protocols that can fend off a single drone or even a swarm of drones from the guarded premises,” IAI said in its statement.
First revealed to Jane’s at ELTA’s Ashdod facility in southern Israel in late 2015, the Drone Guard is available for the short-, medium-, and longer-range detection and flight disruption of UAVs. It can be used against single threats or against multiple threats coming from different directions.
The system uses one of these three radar systems: the ELTA ELM-2180M man-portable radar to detect targets with a very low radar cross-section (RCS) out to a range of 3 km; the ELM-2026B radar for the detection of similar-sized objects out to about 4.5 km; or the ELM-2026 to do the same out to 6 km. For countering small UAVs, each of the radar systems is upgraded with special detection and tracking algorithms, as well as being adapted with an EO sensor for visual identification.
All three solutions utilise 3D (azimuth, elevation, and range) X-Band radars (for ground-clutter removal and separation between ground and air targets) to detect low-flying and low-speed airborne targets with a small radar cross-section (RCS). When an unauthorised UAV is detected and tracked, the ELTA system then sets about jamming it to cause the aircraft to either return to its point-of-origin (the ‘Go Home’ function) or to shut down and land.
