Dealing with military and asymmetric threats represents a key issue for any military vessel in various environment. In
order to support ship's self protection, Thales has designed a new generation of naval InfraRed Search and Track (IRST)
called ARTEMIS. It has been selected to equip Future European Multi Roles Frigates (FREMM).
ARTEMIS is a fully new passive staring IRST system capable of automatically detecting and tracking both air and
surface targets simultaneously. It is able to detect and track maneuvering and stealthy new threats as well as surface
asymmetric threats.
The paper describes the novelties of the ARTEMIS staring architecture and some of its technologies. It describes also
the advantages offered by this new concept of electro-optical surveillance with full static sensor heads compared to
existing and future solutions, and its capabilities to comply with future integrated masts standards.
The paper concludes by a presentation of the product for the French Navy.
We report of a ship borne off-axis laser warning sensor designed and built at Onera. Classical laser warning sensors
detect a laser beam when it is illuminating the warning sensor, meaning that the sensor is located along the laser
propagation axis. Hence, large ships are difficult to protect since they require multiple laser warning sensors installed at
various locations on the ship hull. On the contrary, the off-axis sensor collects the Mie scattered flux out of the beam
propagation axis and looks at the beam sideways. Therefore it can be designed so as to protect the whole ship with only
one sensor covering 360°. This paper describes the system and the instrument performance model in maritime
environment. Field trials off the Mediterranean coast were conducted by Thales Optronique in fall 2007 in order to
validate the concept in operational conditions.

This paper describes technologies than has been introduced in ARTEMIS design (large IR FPA, original optical design,
electronic stabilization, dedicated algorithms on COTS processing boards). It also describes the advantages offered by
this new concept of electro-optical surveillance with fully static sensor heads compared to existing scanning solutions
from a technical, operational and logistics point of view.
