Surface Radars Ground Based Defence Radars - Naval Defence Radars

Threats are increasingly varied (particularly in the field of drones), discreet or even stealthy, fast, and capable of sudden maneuvers. Moreover, theaters of operation are evolving, from land-based "pitched battles" to "diffuse" theaters, and from naval battles to near-coastal operations.

In this complex environment, radars are evolving in six main directions.

• The use of passive radars, which exploit the emissions of other users of the electromagnetic spectrum, turning the disadvantage of spectrum congestion into an operational advantage: discreet, they can "see without being seen".

• Intelligent" use of radar resources. Cognitive radars" exploit not only the data they have acquired on the operational terrain (terrain reflectivity, target density, trajectories...
