US delivers anti-mortar radars to Ukraine: Pentagon

The US military has delivered three radars to Ukraine designed to detect incoming mortar fire, the Pentagon said Friday, amid appeals from Kiev for Washington to send weapons to help fight pro-Russian rebels.

The counter-mortar radar systems were flown to Ukraine in a C-17 cargo plane that accompanied US Vice President Joe Biden, who paid a visit to Kiev on the first anniversary of protests that unleashed a year of upheaval.

A total of 20 counter-mortar radar systems were due to be delivered over the next several weeks, and Ukrainian troops would undergo training on the radars starting in mid-December, Pentagon spokesman Colonel Steven Warren said.

The radars detect incoming mortar rounds and then calculate the origin of the mortar fire. The systems can be hooked up to mortar or artillery batteries which then return fire.

“It will be up to the Ukrainians how, when and where they deploy these systems,” Warren said.

President Barack Obama has so far ruled out providing weapons and ammunition to Ukraine, and instead approved the delivery of “non-lethal” assistance such as radars, night vision goggles, radios, rations, body armor and other items.

But at a Senate Foreign Relations Committee hearing earlier this week, Tony Blinken, who is nominated for a senior diplomatic post, said the United States should consider providing Ukraine with “defensive” weapons.

“I think it is something that we should be looking at,” Blinken said.

Ukrainian leaders and some US lawmakers have repeatedly urged Obama to send arms to the Kiev government but the Pentagon said there had been no change in the current approach.

“To my knowledge, there is no new policy decision to announce,” Warren told reporters.

Russia, which denies Western accusations it is supplying and advising rebels in eastern Ukraine, has warned the Americans against arming Ukrainian government troops.

Ecuador opens tender to acquire radars

By on Thursday, October 9th, 2014

Ecuador has opened a tender to acquire a radar system to combat drug smuggling, after a multi-million-dollar deal with China fell through, the defense minister said Tuesday.

Plans to buy four radars from China for $60 million were canceled last year after Ecuador found they were incompatible with its military aircraft.

Spain, France and Italy have been invited to submit bids for the radar system, a process which Defense Minister Fernando Cordero said opened on October 1.

“Ecuador in a few months will have a radar system that covers the entire national territory,” Cordero said.

The radars would be used to guard against drug flights from Ecuadoran air space, as well as protect the country’s borders.

The government of President Rafael Correa decided to acquire the radars following a 2008 cross-border raid by Colombian forces on a leftist FARC guerrilla encampment inside Ecuador.

The attack resulted in 25 deaths, including that of a top FARC leader, and caused a diplomatic crisis between Bogota and Quito.

Correa is in the process of modernizing Ecuador’s military and plans to invest $1.6 billion in upgrades through 2017.

Selex to Upgrade NATO Radars in Turkey

By on Wednesday, June 18th, 2014

Selex ES has signed a contract worth approximately 12 million Euros with the NATO support agency NSPA to modernise three RAT 31 DL three-dimensional air defence radar systems. The radars are currently in active service in Turkey following a contract signed in 1995.

The modernization program will align the three systems to the latest NATO standards, further optimise operating costs and significantly improve procedural and maintenance times.

Thanks to this upgrade, the life cycle of the radar systems will be significantly extended, ensuring continuity of operations within NATO’s air defence network and improving the overall availability of the systems.

This performance upgrade is possible due to the flexibility of the system architecture chosen at the time the radar was originally supplied. This modular architecture allows Finmeccanica – Selex ES to easily address and implement evolving customer requirements, minimising the through-life cycle costs of the system.

The RAT 31 DL radar is a member of the Finmeccanica – Selex ES family of proven and successful long-range 3D radar systems. It is available in fixed FADR (Fixed Air Defence Radar) and mobile DADR (Deployable Air Defence Radar) configurations.

Selex ES sold more than 50 long range radar systems in the world so far. In particular, RAT 31 DL is currently in service in several countries, eight of which are NATO members. The radar covers an area of around 500km and offers advanced features such as electronic countermeasures and anti-radiation missile capabilities.

The Indonesian Navy (Tentera Nasional Indonesia – Angkatan Laut: TNI-AL) will equip a total of four Ahmad Yani (Van Speijk)-class guided missile frigates and one Kapitan Pattimura (Parchim I)-class corvette with low-probability-of-intercept (LPI) naval radars.

The radars will be built by Indonesian naval sensor manufacturer PT Infra RCS, company officials told [i>IHS Jane’s on 11 April.

The company describes its equipment, the IRCS LPI Radar, as a stealthy sea-based X-band (SBX) radar with frequency modulated continuous wave technology.

“It has a maximum power output of only 10 W, making it quiet and virtually invisible to radar warning receivers on enemy vessels”, said Prihatno Susanto, Technical Advisor for the company. “This allows our warships to detect hostile surface combatants without being discovered”.

The IRCS LPI Radar has an effective range of 24 n miles and is equipped with tracking software known as Maritime Tracking Aid that allows for automatic radar plotting aid functionality. The system’s antenna rotates at 20 rpm and has a gain of about 30dB.

The radar is available as a stand-alone system but can also be integrated with a vessel’s electronic chart display and information system (IRCS) and combat management system.

The vessels now equipped with the radar are the guided missile frigates KRI Ahmad Yani and KRI Abdul Halim Perdanakusuma. Both began upgrade works in December 2013. Undergoing the equipment fixture currently are similar vessels in class KRI Yos Sudarso , KRI Oswald Siahaan and the Kapitan Pattimura-class corvette KRI Sultan Taha .

Besides LPI naval radars, the company has also won a contract to equip Oswald Siahaan and Yos Sudarso with naval electronic support measures (ESM) systems that can detect electromagnetic emissions from electronic devices on enemy ships such as radar, communications equipment, jammers and missile targeting systems.

“The IRCS ESM has electronic intelligence (ELINT) capabilities that can pick up signals emitted by hostile warships from up to 90 n miles away via a passive radar”, said Susanto. “Once these electromagnetic emissions are detected, a computer software that comes with the system will be able to identify, classify and pin-point the exact location of the source for commanders to take action.”

The company has indicated that it is currently embarking on an effort to market both systems internationally.

Telephonics Corporation announced Wedensday, January 9, that its AN/ZPY-4(V)1 multi-mode maritime surveillance radar for was selected by Northrop Grumman to equip the US Navy’s MQ-8B Vertical Take-Off and Landing Tactical Unmanned Aerial Vehicle (VTUAV) as part of the US Navy Fire Scout radar “Rapid Deployment Capability” program. Northrop Grumman awarded Telephonics $33 million to provide the development, production, integration and testing of nine radar systems. For the larger version of FireScout known as MQ-8CNorthrop Grumman has pitched a different system – a variant of its own AN/ZPY-1(V) (STARlite). The selection of the radar built by Telephonics followed successful demonstration of the radar on the MQ-8B during flight trials conducted in September 2012.

Telephonics originally developed the  X-band RDR-1700B as a lightweight (34 kg) radar for search, surveillance, tracking, imaging and weather avoidance applications. For the AN/ZPY-4(V)1 configuration the RDR-1700B+ received a Ground Moving Target Indicator (GMTI) mode, providing the FireScout operators the capability to move seamlessly from blue water, to shoreline, and to overland missions. The GMTI mode allows automatic detection and tracking of moving targets, using ground clutter cancellation techniques.

Moreover, the AN/ZPY-4(V) is planned to include automated classification aids and sensor management capabilities being developed in cooperation with the U.S. Navy that will further improve Intelligence, Surveillance, and Reconnaissance efficiency. Supporting operations in a dense littoral target environment is supported using the U.S. Navy’s Ocean Surveillance Initiative (OSI) software that is fully integrated into the radar. This provides the unique integration of ship Automatic Information System (AIS) data providing rapid identification of threats with minimum operator workload.

When integrated with other on-board sensors, the radar increases the VTUAV surveillance area rate coverage and operator efficiency by pointing the EO payload to points of interest detected through the radar’s wide area scan.

“The integration of the AN/ZPY-4(V)1 multi-mode radar onto the MQ-8B Fire Scout will bring an all-weather sensor that provides wide area situational awareness capability to the platform” said Kevin McSweeney, Telephonics’ Chief Operating Officer.

A new radar system from Telephonics will enhance night and all-weather capabilities of the Navy's Vertical Take Off and Landing Unmanned System (VTUAV).
