The EL/M-2238 3D-STAR is a versatile naval radar system designed by IAI Elta for medium-sized warships, including corvettes and frigates. The acronym STAR denotes Surveillance & Threat Alert Radar.
Design and description
This radar is a fully coherent, multi-mode Pulse-Doppler radar functioning within the S band frequency range (2-4 GHz), enabling concurrent detection of both aerial and surface targets. It integrates with anti-air defense and surface-gunnery platforms. The antenna employs a planar array for 3D multi-beam scanning alongside a vertical strip radiator array. Equipped with programmable signal processing, it maintains stabilization across roll and pitch angles up to 20 degrees. The system is offered in three configurations—large dual-face, medium, and small single-face—to accommodate various vessel types.
