Reutech launches new naval surveillance radar
Thursday, 20 October 2005

Cape Town
Reutech Radar Systems of South Africa has launched a new naval X-band surveillance radar, drawing on its experience of air-defence radars, naval trackers and related systems.

The RSR 210N is a lightweight multimode 2D radar aimed at small surface combatants operating in the littoral environment, naval support vessels, and coast guard patrol vessels. It is also intended for use as a secondary radar on larger combatants and as a helicopter control radar. It has already drawn serious interest from two European navies.

The RSR 210N can be used as a stand-alone surveillance system on a small vessel, or can be integrated into a combat management system (CMS). It has separate air and surface channels, each able to deal with more than 200 tracks, automatic target classification (surface, rotary wing, fixed wing) and automatic or manual track initiation. It offers instrumented ranges of 2 km to 50 km in the air/sea surveillance mode, 1 km to 30 km for anti-aircraft self-defence, 1 km to 25 km for gunfire support, and 50 m to 10 km when used for helicopter guidance. The antenna rotation rates are 15 rpm for surveillance, 30 rpm for anti-aircraft self-defence, and 60 rpm for gunfire support and helicopter guidance. Accuracy is claimed as better than 0.3º in azimuth and better than 15 m in range.

Key elements are an 8 kW nominal output air-cooled travelling-wave tube amplifier, a multichannel receiver/exciter with pulse compression and a fully coherent Doppler software signal processor. A comprehensive electronic counter-countermeasures suite is integrated, and the system has extensive on-line built-in test with integrated diagnostics.

The antenna is a composite shaped reflector with a 2.8 m x 0.7 m aperture, using switched linear horizontal/circular polarisation, stabilised in roll to 30º and giving better than 1º stabilisation accuracy. The antenna/pedestal structure is 2 m high with a swept radius of 1.5 m, and weighs less than 300 kg. The below-decks elements take up 1.8 m x 1.3 m x 0.65 m and weigh less than 750 kg.

Options include a stand-alone console when the system is not integrated into a CMS; 'identification friend or foe', supplied or customer-furnished, offering plot integration with primary or separate interface and a direct control interface to the CMS; and two-axis stabilisation.

The radar has been developed on the basis of proven building blocks and technologies drawn from a number of sources. These include:
* Reutech's RTS 6400 tracker fitted to the South African Navy (SAN) patrol corvettes;
* the K130 stabilised platform (for the German Navy K130 corvettes);
* the Page battlefield processor developed for Thales Netherlands (as part of the South African Army's ground-based air defence system);
* the RRP 200 signal processor developed for EADS to give a European coastal surveillance radar system air surveillance capability;
* experience gained on the ESR-220L radar for the South African Army; and
* the system integration experience gained from the SAN patrol corvette programme.
