His Excellency Ambassador
of the Republic of Indonesia,
Mr. prof. Hamid Awaluddin
Your Excellency!

Taking an opporftrnity we would like to express our respect
to you and your
country' Thank You for the interest to our company and our production
and giving us
an opportunity to conduct negotiations with your representatives.

As a result of negotiations held by our representatives Mr. Evgeny
Hromov and


vladimir Yudin with Mr. Dian wirengiurit we offer for the beginning
to start
cooperation in the field of over-the-horizon radio location on
the basis of over-thehorizon radar "Laguna".

"Laguna" is the modem, highly efficient, civil used OTH surface-wave
radar
specially designed for ensuring of law and order, as well as economic
security in the
200-miles exclusive economic zone of coastal states.

We suggest discussing of different versions of cooperation including joint'
development and production of "Laguna" radax's necessary parts
and equipment.

In

case

of


interest

of

Indonesian authorities

or private companies in

this

cooperation we are ready to start negotiations both in Indonesia and in
Russia at any
appropriate time for you.

Yours respectfully,
Sergei O. Tishenko

Currently, surface and air situation in the 20G'mile zone is controled by means of shore and ship
radars, surveillance airplanes, and satellite intelligence.

Longstanding experience of using these traditional means of monitoring revealed a nurnber of
shortcomings:

o Coastal microwavs radars are not able to carry constant monitoring of the
200-mile zone, as well as can detect targets at the ranges of up to 50 mlles and
have limitations of uninterrupted operation time, meteorological and noise conditions.

r The use of patrol aircrafts and coastguard ships is
more effective, but continuous monitodng throughout the
maritime domain awareness is extremely expensive.

r Satellite observing of the coastal zone is not available to all states for its
exclusivity and high cost and often used to possess strategic solution ratherthan
to solve tasks of the local natur6,

To meet the challenges of economie security of
coastal state the Open-stock company )

RADAR OPERATION PRINCIPLES
Funclioning of OTH SW radar is based on the ability of short-range radio waves to spread beyond
horizon along the sea surface by using diffraction efiect.
It makes enable to detect targets, placed at a considerable distance over the horizon and in direct
field of vision.

RADAR MAIN MISSIONS:

. detection and tracking of ships and aircrafts in the zone of control;
r automated measurement movement coordinates and parameters of detected ships
and aircrafts;
o classification of detected ships and aircraft on lhe basis of "small"-"big", "maritime"-air";

r

ships and planes tracking information transfer to the external control posts for collection

and processing of information to make operational decisions;
. analysis and estimation of the HF signals level distribution to ensure electromagnetic
compatibility of radar "Laguna" with other radio assets;
r analysis of meteorological conditions of the sea surface in the zone of control-

RADAR *LAGUNA'' STRUCTURE
SW radar "Laguna" is located on the coast. The radar composition comprises transmitter and roceiving
antenna-feeder devices placed at two sites, power amplifying device, and device for receiving and processing
information.
All radar electronic equipment is placed in two transportable containers.

EOUIPMENT AND OPEMTORS'S WORKBENCHES OF RADAR "I.AGUNA''
The radar electronic equipment produced using
modern Russian and foreign electronic components
are located in the autonomous modules
(containers), appointed by the conditioning, automatic

fire alarm and ffoe-fighting systerns. Upon request of
the Customer radar equiprnent can be placed in the
pre-arranged indoors.

Digital interfaces of radar make possible to

couple various consumes and to supply compatible
systerns and control units with coordinate and tracking

iriformation. lnformation consumers attachment is
performed by communication channels availabb at
the Customer's.

Information consumers attachment is perforrned by communication channels available at the
Customer. lf necessary, communication and data radio transmission means can be provided with the
station.
The functional management, data processing and detected objects display information of the radar
"Lagunan is carriod out by specialized computing complex.

RADAR's ECONOMIC EFFICIENCY

The use of the surface-wave radar trlaguna>r

ensures

substantial savings in manpower, material-technical and financial
resources and also significantly reduces the overall specific cost of
monitoring the surface and air situation. At the same time the
continuily of control is ensured throughout the 200-mile economic
zone.
