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.[1]

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. Tt 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.[2][3]
