South Korea will commence the induction of its new LIG Nex-1 Long Range Air Defence Surveillance Radar (LRADSR) into air force service from 2015, according to company sources speaking to ChainHomeHigh at the Seoul Aerospace and Defence Exhibition held in the South Korean capital between 29th October and 3rd November.
The LRADSR is an L-band (1.215-1.4 gigahertz) system which has a range of circa 200 nautical miles (370 kilometres) and a ceiling of 100,000 feet (30,480 metres). This three-dimensional radar uses an Active Electronically Scanned Array antenna. The LRADSR is being procured to eventually replace the Lockheed Martin AN/FPS-117 L-band air surveillance radars which the Republic of Korea Air Force (ROKAF) currently uses. In terms of performance, the LRADSR has similar capabilities to the AN/FPS-117.
Over the longer term, the ROKAF plans to induct LIGNex-1’s Medium Range Air Defence Surveillance Radar (MRADSR) into service which will have a shorter range of around 76nm (140km), and a 40,000ft (12,192m) ceiling. The MRADSR is an S-band (2.3-2.5/2.7-3.7ghz) radar. There is no word on when this radar may enter service nor on how many of the MRADSR and LRADSR the ROKAF may procure. As well as manufacturing the radar, LIG Nex-1 built the Identification Friend or Foe (IFF) interrogators for both systems.
These radars will join the Israel Aerospace Industries Elta Systems two EL/M-2080 Green Pine ballistic missile defence radars which have been undergoing testing in South Korea. The EL/M-2080 has a range of circa 270nm (500km), according to open source reports.
