Israel Aerospace Industries (IAI) has unveiled a new version of its ELM-2112 ground surveillance radar that is designed to detect threats moving through foliage, saying it has been "operationally deployed for several years".
Using frequency modulated continuous wave (FMCW) technology, the ELM-2112FP "enables personnel and vehicle movements to be detected for up to several kilometers in forested areas, in real-time and irrespective of whether or not there is a clear line-of-sight," IAI said in a 14 March press release. Its range depends on the type and density of foliage.
Noam Donenfeld, business development manager at IAI-Elta's Land and Naval Radars and Systems Division, said the radar is already in service with multiple customers he declined to identify and said it operates on the L band frequency, unlike other radars in the family, which operate on the X and C bands.
"The idea is a penetrating surveillance detection ability based on a single, very wide staring beam," he said. "This lights up the target."
Noting that previous foliage-penetration radars were carried by aircraft, Donefeld added, "What is unique here is that it is ground based and can be affixed on top of a pole, peering into a forest and detecting targets." Weighing 65 kg, it can also be mounted on vehicles.
Donefeld said that objects must be moving in order for the ELM-2112FP to detect them. "Like all ground radars that look at field targets, this is activated by Doppler," he said.
The IAI press release quoted a commander in charge of a border protection system that uses the radar as saying, "Using this radar has opened our eyes in places that were so far beyond our vision; this system has huge operational value."
