Selex RAN-40L is a naval 3D L band search radar developed by Leonardo.

[2] The radar is used for long range maritime air surveillance and early warning.

The radar uses a fully solid state active phased array antenna and capable of tracking and detecting air targets like aircraft or drones up to 400 km away.

RAN-40L is based on existing land based 3D RAT-31DL radar which is a system widely used by NATO Countries for long air surveillance.

Radar coverage is obtained by phase scanning in elevation, while mechanically rotating in azimuth.
