South Korea – New IFF Transponder

The Republic of Korea has awarded a contract to Telephonics Corporation for the integration of the company’s AN/UPX-44 Identification Friend or Foe (IFF) transponder onto undisclosed ground-based air surveillance radars operated by the country.

The AN/UPX-44 can work with the United States’ Next Generation Air Transportation System’s Automatic Dependent Surveillance Broadcast (ADS-B) air traffic management architecture, along with Mark XIIA IFF Mode-5 and Mode-S military and civilian transponders.

There is no word regarding which radars will be equipped with the AN/UPX-44 IFF, the value of the contract, how many systems will be delivered or when deliveries will commence and complete.

Italy – Galileo Let Me Go

In late October Selex Galileo performed flight tests of its Falco Unmanned Aerial Vehicle (UAV) equipped with the firm’s Gabbiano T20N radar.

The Gabbiano X-band airborne radar family can equip both UAVs and manned aircraft. It is intended to support maritime patrol and homeland security missions.

The radar has a low probability of interception via its frequency agility and jammer avoidance functions. Offering a range of up to 407 kilometres (220 nautical miles), the antenna’s blind zone is a mere six metres (19.6 feet) in the T20 configuration, and 75m (246ft) for the T200 Gabbiano variant (see below). Spot and strip synthetic aperture radar modes are integral to the radar, as is a ground moving target indicator.

As noted above, the family includes the T20 and T200 products. The T20 includes a belly-mounted 360º and a 90º nose-mounted antenna with a weight of 43 kilograms (94.6 pounds). Its transmission power averages 20 watts and the radar uses a solid state power amplifier. The belly-mounted antenna for the T200 weighs 62kg (136lb) with the nose-mounted antenna weighing 56kg (123lb). Transmissions are generated by a travelling wave tube with an output of 200W when using peak power management.

Russia – Surok Keeps Watch

Russia’s Radio Technical and Information (RTI) Systems Joint Stock Company has unveiled the ‘Surok’ (‘Marmot’) air surveillance radar.

The Surok is designed to detect and track targets using a small mobile radar. In terms of performance, it is reportedly capable of detecting and tracking a target flying at 656ft (200 metres) altitude at a distance of twelve kilometres (6.4 nautical miles). Targets flying at 3,280ft (1,000m) altitude can be detected at 20km (10.7nm), and those flying at 5,000m (16,404ft) at 50km (26.9nm) range.

The rationale behind Surok’s development was to design a mobile radar that provides 360º protection for critical infrastructure. Although there are several, deployable military products which can perform such a function, RTI Systems’ radar intends to provide this protection using a lower-cost approach.

Euronaval: GEM Elettronica Planning New Sentinel Family Member

Italian radar specialists GEM Elettronica is planning a new addition to the company’s Sentinel family of naval radars.

The firm told ChainHomeHigh at the Euronaval exhibition in Paris that they are developing a new three-dimensional X-band surveillance radar which they hope will be available for purchase next year. The radar is being aimed at customers requiring either vessel-mounted navigation or shore-based coastal surveillance systems.

This new product uses a phased-array antenna, and has low sidelobes and frequency agility to reduce detection and enhance the radar’s electronic counter-counter measure performance. An optional transponder antenna can be fitted, and the radar comes equipped with a navigation antenna.

GEM Elettronica told ChainHomeHigh that they have yet to name their new product, although they will reveal a designation when the radar becomes formally available for purchase next year. Currently, the firm is in discussions with the Italian Navy regarding the installation of this new system onboard a series of new patrol vessels which will equip the force.

In a separate development the company revealed that one of the coastal radar stations that it had supplied to Libya prior to last year’s civil war had been destroyed by a NATO airstrike during hostilities. GEM Elettronica has installed ten radar stations along the Libyan coast stretching from the country’s border with Tunisia to the Libyan capital Tripoli. The other nine radar stations which had been constructed remain functioning and were not attacked during hostilities. It is believed that the radar station may have been destroyed by an airstrike performed by the Armée de l’Air (French Air Force). GEM Elettronica had been contracted by the regime of former Libyan leader Colonel Muammar Gaddafi to build a coastal surveillance radar network along the Libyan coast involving up to one hundred radar stations. The company hopes to reactivate this contract at some point in the near future, although it says that because of Libya’s currently complex political situation, this may not happen at any point soon.
