capabilities, for both national and worldwide international customers. In addition to being the main sensor for Rafael Iron Dome, the ELM-2084 performs the same function for Rafael David’s Sling air and missile defence system and IAI’s Barak weapon family systems. The latest addition to the S-band MMR family of multifunction AESA radars is the full-digital ELM-2248LB Digital-MMR (D-MMR). According to Elta it is a four-dimensional (4D) full phased array (both in azimuth and elevation) radar, implementing AESA technology based on Gallium Nitride (GaN) transmitter-receiver modules (TRMs) and scalable solid-state phased array. The D-MMR performs digital beam forming (DBM) by digitally sampling the signal at TRM module level, delivering high situational awareness picture and weapon support for current and emerging threats under severe environmental conditions. Characterized by high mobility and fast deployment, including air transportability with C-130 aircraft, with different power generation configurations on trailer or shelter depending on radar version and customer needs, in the air surveillance mode the ELM-2248 LB radar has an instrumental range of up to 400 km. With a sectorial 120° or 360° azimuth coverage rotating up to 30 revolutions per minute (RPM), the ELM-2248LB features an elevation coverage up to 70° with high accurate 3D measurement and up to 1,100 targets capacity.

to-air missile systems. In the C-RAM mode, the radar has a detection range of 100 km with a 120° azimuth and up to 90° elevation coverage, with a 0.3% CEP and a tracking capability of 200 targets/min. In mid-2019, IAI Elta unveiled another radar derived from the ELM-2084 and called Multi-Sensor MMR, which adds multispectral capabilities to counter emerging threats with the addition of a higher frequency radar, an active IFF, an automatic dependent surveillancebroadcast (ADS-B) receiver, as well as passive EO/IR and signal intelligence sensors, in addition to optional passive sensors for detecting weapons being launched. Shifting to the C-band, the ELM-2311 CompactMMR (C-MMR) exploits the same architecture of the aforementioned radars and is a highly mobile and transportable all-in-one radar system featuring a reduced-sized GaN-based TRM AESA antenna, which together with the power generation unit and two operator consoles including communication equipment, can be installed on board a single vehicle for maneuvering forces. The C-MMR performs the same functions of the bigger versions with reduced ranges. In the air-defence and WLR modes, the system has respectively a 250 and 70 km range with 360° rotating or 90-120° starring antenna modes, up to 50° in elevation and over 100 targets/min. The MMR radar family found international success with over 100 systems sold
The ELM-2084 MMR (Multi-Mission Radar) comes in a family of 3D multifunction radars in both S-Band and C-Band and in different configurations such as the latest Multi-Sensor MMR or the smaller ELM-2311 highly-mobile version. © IAI-Elta
