Naval Radar Surveillance

 

Terma's SCANTER X-band Navigation, Surface Search and Short Range Air Surveillance Radar Systems are complete radar sensor systems with proven small target detection capability to assist authorities in efficiently monitoring illegal activities such as drug trafficking, smuggling, illegal immigrants, piracy, illicit fishing, terrorism, etc.

It is perfectly suited for high-definition sea surface surveillance and short-range air surveillance for helicopter control and ship navigation.

The SCANTER naval radar systems comply with the justification and operational requirements on board naval vessels to:  

• Provide backup to primary surveillance radar system
• Assist on-board tactical task functions
• Helicopter landing control
• Perform sea and short-range air surveillance with automatic target tracking
• Provide versatile interface capability for C-Flex and other on-board systems
• Provide safe navigation for year-round operation.

Ground radar surveillance comprises all radar installations on the ground, irrespective of the installation's target land objects, airborne objects, or objects on or over the water surface. The SCANTER product range comprises the SCANTER 5000 Series Solid State Pulse Compression radar and the combined Sea and Air Surveillance SCANTER 4000 Series radar.

Harbor SurveillanceThe requirements for traffic monitoring in ports and harbors are increasing and have been extended from collision monitoring and grounding prevention, guidance of the port's own pilot boats, monitoring anchoring areas, etc. to generally focusing on the safety and security aspect of the ports as such.

The S-300 is regarded as one of the most potent anti-aircraft missile systemscurrently fielded.^[3] Its radars have the ability to simultaneously track up to 100 targets while engaging up to 12/24/36 targets. The S-300 deployment time is five minutes.^[3]The S-300 missiles are sealed rounds and require no maintenance over their lifetime. An evolved version of the S-300 system is the S-400 (NATO reporting name SA-21 Growler), which entered limited service in 2004.

Numerous versions have since emerged with different missiles, improved radars, better resistance to countermeasures, longer range and better capability against short-range ballistic missiles or targets flying at very low altitude. There are currently three main variations.

This system broke substantial new ground, including the use of a passive electronically scanned array radar and multiple engagements on the same Fire-control system (FCS). Nevertheless, it had some limitations. It took over one hour to set up this semi-mobile system for firing and the hot vertical launch method employed scorched the 

It was originally intended to fit the Track Via Missile (TVM) guidance system onto this model. However, the TVM system had problems tracking targets below 500 m. Rather than accept the limitation, the Soviets decided that the tracking of low altitude targets was a must and decided to use a pure command-guidance system until the TVM head was ready.^[5] This allowed the minimum engagement altitude to be set at 25 m.



The next modernisation, called the S-300PMU (Russian С-300ПМУ, US DoD designation SA-10f) was introduced in 1992 for the export market and featured the upgraded 5V55U missile which still utilised the intermediate SARH terminal guidance method and smaller warhead of the 5V55R but increased the engagement envelope to give this missile roughly the same range and altitude capabilities as the newer 48N6 missile (max. range 150 km/93 mi). The radars were also upgraded, with the surveillance radar for the S-300PMU being designated 64N6 (BIG BIRD) and the illumination and guidance radar being designated 30N6-1 in the GRAU index.

The S-300 missile system is able to hit multiple targets at once, and is typically launched from the back of a truck. The missiles can target aircraft and missiles flying more than 16 miles high, according to specifications published by the American Federation of Scientists, a nonprofit organization that provides analysis on national security issues.
