System TACTICOS :
Design Features. A SEWACO system
comprises primary radar sensors for long-, medium- and short-range air and
surface warning radars, secondary radar sensors such as IFF and helicopter
transponders, ESM and IR sensors linked to the DAISY action information system. This is linked to a weapons control system
including one or more tracking and target illumination radars, CIWS,
electro-optical directors, missile, ECM and gun defenses and
communications/datalink systems.
The heart of SEWACO is the modular Digital Action Information System
(DAISY). DAISY is assigned to present
raw or digitized information from primary or secondary radar sources; to
compile and present tactical air, surface, and sub-surface tactical pictures;
to datalink operations; and to designate targets for on-board weapons systems
and assistance in operations including ASW helicopter direction and tactical
navigation.
The DAISY system comprises a data handling cabinet and a number of
display consoles appropriate to the operational functions of the system. The cabinet contains the data handling
computer (usually a Signaal SMR, although other types can be used), a sensor
data distribution unit, and one or more video extractors.
Two types of display consoles are available, a vertical (VDC) and a
horizontal (HDC) type. The VDC is
equipped with a 7 in
alphanumeric display for presentation of alphanumeric data in tabular
form. The HDC is equipped with one or
two 7 inch
or 15 inch
displays. The main display unit for both
types is a 40 cm
labeled position display or a 40/50 cm unit.
Communication with the data handling unit is by manual input keyboards,
quick-input keyboards, rolling balls, and handwheels. Other input systems such as light pens and
touch-input can be integrated.
Sets of system tasks are defined as system functions (logical
subsystems). Every system function is handled by a data communications network
including high-speed databases and/or direct communications and/or an
intelligent communications handling package. Fail-safe and fail-soft facilities
are provided through duplication of critical parts while parts of the complex
are decentralized to achieve optimum damage control.
The display subsystem consists of SIGHT (Signaal General-purpose
High-resolution Tactical) workstations.
These are color-raster scan type.
Different types of data sources can be simultaneously displayed. Storage for maps, manuals, and procedures is
by optical discs. The workstations
enable multiple system access facilitating operator system access through
modern window techniques. Each workstation
can be used for any system function within the defined security limits of a
given operator. Any SIGHT workstation
can also control the integrated internal and external communications systems.
SEWACO VII is a heterogeneous, mixed architecture system. It uses different types of computer systems
with different operating systems and dual or triple redundancy on all essential
subsystems. SEWACO VII includes two DEC
Minivaxs for management information and support, four Signaal SMR-4 computers
(two for the combat direction core and two for internal and external
communications control), and six Motorola 68030 micros for pre-processing,
sensor management, and bus interfacing.
These are connected via a triply co-axial Ethernet databus with up to
256 32-bit channels and a TV/infra-red video network linking the GOS
workstations.
Operational Features. The front end of the
SEWACO VII system consists of 16 multi-functional General Operator Station
(GOS) terminals, 15 of which are in the ship’s command center, and one in the
communications room for use as a communications management terminal. All these workstations are functionally
interchangeable, their use being determined by the operator’s keycard. There are no separate consoles for individual
weapons systems. Two additional
multi-weapon control system (MWCS) visual display units for diagnostic and
other purposes are linked to two bridge wing target designation sights, the
STIR fire control radars and the gun/missile systems.
When used in AAW mode, SEWACO VII operates a fully automatic threat
evaluation mode with the six most threatening targets within range being
presented for simultaneous engagement.
Parameters used for threat evaluation include area or sector, target
altitudes, speed, and flight profiles. A
filter envelope including speed and range brackets, as well as closest-point-of-approach
criteria, prevents the system being swamped with false targets. Track initiation and engagement can also be
automatically achieved.
In a high-threat environment, a full 360-degree auto- initiation
sector can be set with SEWACO VII. In
force-orientated AAW operations, the system allows tracks to be handed over to
other ships for engagement via a datalink.
LIROD Mk-2 :
Lightweight radar/optronic director
LIROS Mk2 is Thales' lightweight naval fire control tracking system
LIROD
Mk2 can operate either as a main sensor in an autonomous weapon control
system or as secondary sensor, integrated in a combat system
configuration.
It is particular suitable for short range
all-weather operation where high accuracy is required combined with
low-level capability, low susceptibility yo jamming and the possibility
of passive operation. Thanks to its low weight, LIROD Mk2 is ideal for
fire control on small ships.
The accurate target tracking of LIROS Mk2 can be ued for air surface weapon control.
Main features
- High accuracy even at low levels, effected by a very narrow vertical beam of the radar, as well as by optronic tracking.
- Insusceptibility
to clutter, due to pulse doppler tracking, combined with Fast Fourier
Transformation (FFT) data processing and variation of RF frequency.
- Resistance to jamming and other interference, realized through:
- sophisticated ECCM facilities,
- use of optronics as an alternative to radar.
sonar KINGKLIP :
The Hull Mounted Sonar (HMS) continues to fulfil an important role in ASW operations. Today the primary functions of a hull mounted sonar are not limited to the detection of submarines but include the detection of torpedoes and the detection of mine-like obstacles.The primary advantage of the hull mounted sonar is its continuous availability. Its use is not limited by sea conditions.
When the propagation conditions result in a surface channel, the HMS can give the best performance.
The other important factor is the forward coverage.
Being ahead of the propulsion system, the HMS has a preferential
position compared to a towed sonar.
Another important advantage is its use in torpedo
defence: it can detect passively in its own right and, as the
effectiveness of torpedo alert depends on achieving full 360° cover and
an estimate of range, the HMS can supply this when used in conjunction
with a towed sonar.
The active detection capability can also be
important in confirming passive detections and increasing the
confidence in the range estimate.
Another important asset of the HMS is in its role of obstacle avoidance in the near surface part of the water column.
The latest version of TUS HMS / BMS development goes back to year 2000 with the UMS 4132 KINGKLIP.
The KINGKLIP HMS is a bow or keel mounted highly versatile medium frequency sonar to be fitted on board corvettes, frigates and destroyers. KINGKLIP
satisfies the multi-mission, surface combatant requirement for a
traditional ASW capability; It also has a powerful self defence
capability against torpedoes and mine-like objects.
KINGKLIP mainly features:
- A wide suite of long and short pulse shapes
- Beam stabilisation in reception
- Concurrent active surveillance and Torpedo Warning function
- A compact and lightweight keel or bow mounted array
system SCORPION :
System Description :An advanced ECM system offering a range of high
fidelity jamming techniques designed to counter
long range search radars, target acquisition
radars and missile radars operating in both their
search and locked-on modes.
Scorpion 2 can be integrated with any wide-open
ESM system that provides instantaneous bearing
measurements on all intercepted radar emitters
such as the Sealion and Vigile ESM Systems.
The ECM is integrated with the ESM to initiate
acquisition of jamming threats via the ECM’s own
receiver. Threats are processed via the
Techniques Generator and the jamming signal is
output from the Steerable Transmitter

in either a single or dual headed configuration
dependent on the vessel’s size and operational
requirements. The dual headed configuration
requires only a second ECM antenna and ECM
Tracking Antenna.
