Terma Marine Radar Systems

Radar Surveillance

The Terma SCANTER X-band Navigation, Surface Search and Short Range Air Surveillance Radar System offers unsurpassed cost effective performance suited for ship navigation, high definition surface surveillance and air surveillance for helicopter control.

The SCANTER Radar Systems are specifically designed to enter service where the commercial Marine Radar fails to meet the requirements for noise and interference rejection, signal processing, electronic interfacing, signal distribution and resistance to tough environments.

The Terma marine radars are now operational in navies worldwide, including U.K. , Norway , Sweden , Denmark , Mexico , Singapore , Chile , Colombia , Turkey , Greece , Korea , and Finland.

A versatile and modular concept ensures compliance with application requirements and specific customer wishes. The Receiver-Transmitter (RxTx) system configuration ranges from single frequency operation to RxTx systems with dual redundant frequency diversity.

The SCANTER Radar System complies with the justification and operational requirements onboard naval vessels to:

• Provide highly capable backup to primary surveillance radar system
• Assist onboard tactical task functions
• Perform sea surveillance and short range air surveillance with automatic target tracking
• Provide versatile interface capability for C3I (command, control, communication and information) and other onboard systems
• Provide safe navigation for all weather operation

When compared with systems with higher transmitter output power, the increased sensitivity and high dynamic range of the SCANTER Radar System is advantageous, especially considering:

• The need to minimise radar emission while optimising target range detection
• The avoidance of receiver saturation in case of jamming

Terma's range of Slotted Waveguide (SWG) Antennas offers cost effective solutions to increasing demands for performance and reliability. High precision waveguides result in extremely low side lobes, narrow main beam, and uniform beam patterns.

X-band antennas complete with gearbox and azimuth encoders are available for surface ship applications. A SWG antenna featuring cosec2 vertical beam pattern offers improved air coverage onboard naval vessels. A pressure tested X-band antenna is available for submarines.

Small Target Detection in Harsh Weather Conditions

Intensive design and development has enabled Terma to offer a complete radar sensor system with a proven small target detection capability. The system has been designed to assist authorities in the efficient monitoring of illegal activities such as drug and weapon trafficking, smuggling, illegal immigration, piracy, illegal fishing and terrorism, meeting the needs of security organisations to track and follow everything on the ocean surface, including very small, slow or fast moving craft.

Terma's naval and costal surveillance systems minimise effect of reflections from large targets like coasters, ferries, large cargo vessels or tankers, increasing probability of detection of nearby small targets. This feature provides the means to cost-effectively detect and track targets both on the surface and in the air.

To comply with requirements for small target detection even in harsh weather conditions, Terma has developed efficient radar signal processing techniques and large high gain antennas with either horizontal or circular polarisation and the use of advanced tracking techniques, including parallel trackers individually optimised for different types of targets.

SCANTER 4100

The Scanter 4100 new generation of Surface Search and Air Surveillance radars has been installed onboard one of the Brazilian Navy's Niteroi class frigates and was selected by the Royal Navy as part of the command and control system for the new Ocean Patrol Vessel (Helicopter) OPV(H), which will go into operational service in the South Atlantic in 2007.
