The EL/M-2238 3D-STAR is a multi-purpose air and surface-search naval radar system developed by IAI Elta for medium-sized ships like corvettes and frigates. STAR is an acronym of Surveillance & Threat Alert Radar.{{cite web|title=EL/M-2238 STAR|url=http://www.iai.co.il/35113-39790-en/MAKS2009_Products_Radars.aspx?btl=1|publisher=IAI|accessdate=18 July 2013}}
Design and description
It is a 3D multi-beam and multi-mode fully coherent pulse Doppler search radar which functions in the S band (2-4 GHz). It can perform both surface and aerial search simultaneously. It is designed to support anti-air and surface-gunnery systems. The antenna in the Doppler sensor has a planar array for 3D multi-beam operations and a vertical array of strip radiators. It has programmable signal processing and is stabilized within a roll and pitch of 20 degrees. It comes in three variants - a larger dual-face version, a medium version and a small single-face version.{{cite web|title=EL/M-2238 STAR|url=http://www.iai.co.il/sip_storage/FILES/3/36843.pdf|publisher=IAI|accessdate=18 July 2013|archive-url=https://web.archive.org/web/20121224190120/http://www.iai.co.il/sip_storage/FILES/3/36843.pdf|archive-date=24 December 2012|url-status=dead}}
