SCOUT Mk2
General
SCOUT Mk2 is a unique surface surveillance and tactical
navigation radar that has true Low Probability of
Intercept (LPI) characteristics. The SCOUT Mk2 radar
uses the Frequency Modulated Continuous Wave
(FMCW) principle enabling to ‘‘see without being seen’’
due to the extremely low transmitter power. This feature
makes interception by ESM equipment or Anti Radiation
Missiles virtually impossible.
The outstanding LPI characteristics of SCOUT Mk2 make
it an excellent choice for covert operation. Just like
passive-optical systems, SCOUT Mk2 can be used under
radar silence conditions, but has both a range and allweather
advantage over optical systems.
SCOUT Mk2’s range resolution cell size of only 6 metres
at 12 nm not only results in an excellent capability to
distinguish closely-spaced targets, but also offers good
detection of small targets in heavy clutter.
While in the past decade, low visibility has gained an
ever-increasing interest in platform design, SCOUT Mk2
lends its user an open eye to the surroundings, even
under strict EMCON conditions.

A lightweight and versatile radar like SCOUT Mk2 can be used in
many other roles in both static and mobile applications.
These include: littoral surveillance and coastal defence, harbour
and river surveillance, battlefield surveillance, counterdrugs
operations, helicopter approach radar, etc.
Main characteristics
• Low Probability of Intercept, with selectable transmit power,
down to as little as 10 mW
• Extremely high range resolution
• High reliability, low weight and safe maintenance (no lethal high
voltages) due to completely solid-state design
• Low Radiation Hazard
• Can be integrated with I-band pulse navigation radars, using
SCOUT Mk2 Antenna System for pulse and LPI operation
• May be used stand-alone or integrated with a C2 systems.

Technical Aspects
SCOUT Mk2 operates in I-band (former X-band). The
transceiver is located in the dual array antenna to prevent
unnecessary losses in long waveguide runs. This also ensures
ease of installation. The connection to the below deck equipment
is made by a single, thin cable. There are no waveguides
present, unless the system is combined with a pulse transceiver.
The dual array antenna guarantees optimal isolation
between the receive and transmit path, which is essential for
good long-range performance of an FMCW radar. Due to the
fully solid-state design, MTBF is in excess of 10,000 hours.
Configuration
SCOUT Mk2 is available as a stand-alone system or as a fully
integrated navigation and LPI radar system. The radar has
been integrated with several navigation radars while integration
is possible with most commercially available navigation radars.
Video data and track data are available for integration with a
Command & Control systems.
Performance Data
The maximum instrumented range is 24 nautical miles. Detection
range is normally limited by the horizon. Due to the continuous
wave transmissions, the minimum range is unusually
short, as little as a few metres.
