The EL/M-2090 TERRA is an Israeli ground-based very long range early-warning radar system produced by Elta Systems, a subsidiary of Israel Aerospace Industries IAI. It is composed of two radars: the UHF Ultra and the S band SPECTRA. TERRA's performance is achieved through automatic handover and redundancy between the ULTRA and SPECTRA radars, combined with improved target load sharing, Electronic counter-countermeasures (ECCM) and severe-weather resilience.{{cite web|url=http://www.iai.co.il/2013/32981-46515-en/MediaRoom_News.aspx|title=Israel Aerospace Industries Ltd. - Home page : Israel Aerospace Industries Ltd (IAI) Media Room|website=Iai.co.il|accessdate=1 December 2017}} The system can be used for ballistic missiles and space objects detection and tracking at very long ranges.{{cite web|url=http://www.iai.co.il/2013/32981-46466-en/MediaRoom.aspx|title=Israel Aerospace Industries Ltd. - Home page : Israel Aerospace Industries Ltd (IAI) Media Room|website=Iai.co.il|accessdate=1 December 2017}}

Both Spectra and Ultra are active electronically scanned array (AESA) radars that are made up of thousands of transmit/receive modules and use gallium nitride technology (GaN) to enhance their efficiency.{{cite web|url=http://www.janes.com/article/55881/iai-unveils-its-terra-dual-band-long-range-radar-system|title=IAI unveils its Terra dual-band long-range radar system - Jane's 360|website=Janes.com|accessdate=1 December 2017}}
