ELM-2258
The ELM-2258 or “ALPHA” (from Advanced Lightweight Phased Array) is an operating in S-Band rotating multi-function solid-state active electronically scanning array (AESA) radar system for the new generation of medium-sized combat ships such as corvettes, frigates and larger vessels. It consists of a lightweight active phased array and employs multi-beam and pulse Doppler techniques. It also includes robust electronic counter countermeasures (ECCM) techniques and detection capability against low Radar Cross-Section (RCS) targets in complex clutter and jamming environments.
This Software Defined Radar will replace all those radars with a single system, more reliable, flexible and agile.
