Whenever the hard kill of sea skimmers calls for uncompromising accuracy under adverse multipath, ECM or weather conditions, ELTA's STGR is the ultimate Fire Control Radar to accomplish the task.

The STGR is an extremely accurate, monopulse, dual-band (X & Ka) coherent pulse Doppler radar.

The STGR is capable of tracking highly maneuverable targets after fast automatic acquisition, guiding missiles and directing guns against air and surface targets.

ELTA developed the STGR as part of the BARAK-1 Point Defense Missile System for Israeli Navy missile boats.

Operational Capabilities

Survival - particularly under saturation attack - is dependent on fast and reliable automatic threat alert.

Modern sea skimming missiles are the most lethal threats to ships of any Size. High diving non-radiating threats such as Anti-Radiation Missilcs (ARMs) and TV-guided smart bombs, require extended 3D elevation coverage of up to 70°.

Reliance on ESM, optronics or classical radars no longer ensures adequate reaction time lor the ship's self-defence systems due to the limitations ot these sensors. e.g. under various weather conditions, against non-radiating threats, etc.

One has to definitely spot the threat in order to stop it.

Main Features

ELTA's AMDR provides fast detection and automatic threat alert of air targets with a false alarm rate ot less than one per day. This is achieved through the use of unique waveforms and signal and data processing techniques

Combined with excellent tracking capability of more tha 100 surface and air targets, the AMDR is the most cost-effective solution for

Typical Performance

Fighter alcraft detection at 70 Km 
Automatic threat alert of attacking missile at 20 Km with
less than 1 false alarm per day 
Surface target detection up to radar horizon 
Track-While-Scan (TWS) for 100 air and surface targets

Naval forces need a rapid patrol craft response to guard fishing fields, prevent piracy and perform other coast guard roles. The demand for a medium range surveillance radar with fire control capabilities against surface targets has now been met by ELTA's Surveillance and Gunnery Radar System (SGRS).

The SGRS is a lightweight fully coherent pulse Doppler, multimode X-band search radar. It is capable of performing accurate gunnery spotting while scanning against surface targets.

The SGRS is a very cost-effective solution for:

Main Features

The SGRS provides outstanding surface target detectionand extremely accurate tracking and splash spotting. It also performs medium range detection and tracking of air targets.

Typical Performance

The STAR is a fully coherent S-band pulse Doppler 3D multibeam and multimode search radar. The radar performance Long Range air surveillance combined with surface surveillance and, at the same time, provides fast detection and automatic threat alert of air targets with an extremely low false alarm rate. The STAR supports surface gunnery engagement and anti-air warfare by excellent designation to the fire control system.

The STAR, with its superior tracking capability of surface and air targets, is the most cost-effective solution for medium-size ships (Corvette-Frigate), serving as the surface/air search radar, in addition to its threat alert and surface gunnery support roles.

The STAR's azimuth and elevation track accuracy and its high update rate, make it an excellent designator for anti air & anti missile weapon and for ECM or chaff systems.

Main Features

The STAR provides long range detection, high quality missile detection and designation, automatic threat alert, track while scan of air and surface targets and high spatial resolution and accuracy.

Radar Configuration

The STAR is available in single or dual face antenna configurations. The dual face antenna configuration provides double update rate, has two radar transmitters and provides simultaneous Threat Alert and Long Range detection while search, by waveform optimization and inherent radar redundancy. Both configurations are available in two antenna sizes: large or medium size.

ELTA REVEALS FOURTH GENERATION NAVAL RADAR ELTA Electronics Industries, a subsidiary of Israeli Aircraft Industries, of Ashdod, Israel, has recently sold a number of its EL/M-2238 STAR Naval Multipurpose Surveillance Search and Threat Alert Radars to several customers worldwide.
The STAR is a fully coherent S-band pulse-Doppler multi-beam multi-mode and multi-function radar. 
The radar performs long range surface and air surveillance in azimuth and elevation, provides fast detection and automatic threat alert of air targets and sea skimming missiles, and at the same time serves as designator for the ship's surface gunnery and anti air/anti missile fire control systems. 
This combination of functions, formerly requiring two separate radars, makes the STAR the ideal cost effective solution for small and medium size ships, where space and mast-top weight and area is at premium. 
The STAR features include 3D surface and elevation coverage and detection of air and surface targets, automatic multiple target track -while scan (TWS), very low false alarm rate, automatic designation to the ships' weapon systems and interface capability with other sensors. 
The selection of S-band, and combination of pulse-Doppler configuration, advanced programmable signal processing and waveform programming capability, ensures peak performance even in extreme weather and clutter conditions. 
ELTA has accumulated vast experience in the design, development and manufacture of advanced, state-of-the-art naval radars, and the STAR is a fourth generation in this line.
The STAR is currently in series production, and attracts high interest among naval operators around the world.

This digital, compact, cost-effective and user-friendly system is the 3rd generation Coastal Surveillance Radars.It incorporates ELTA's vast experience in surveillance radars and utilizes the company's high resolution technology.

The radar features continuous, gap free, automatic detection and tracking of targets, providing a reliable tactical situation display with a very low operator workload.
