SMART-L (Signaal Multibeam Acquisition Radar for Tracking, L band) is a long-range naval search radar introduced in 2002 by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal).
Design
The digital antenna array has 24 elements; all are used for reception, while 16 are used for creating virtual receiver beams through digital beamforming. The beams' vertical elevation, and compensation for ship movement, is done electronically. Horizontal training is done by mechanically rotating the entire array.[citation needed]
As designed, SMART-L has a maximum range of 400km (220nmi) against patrol aircraft, and 65km (35nmi) against stealthy missiles. A software upgrade, Extended Long Range (ELR) Mode, extends the maximum range for the detection of ballistic missiles to over 2000km, since 2018 all four Zeven Provincien class Frigates of the Royal Netherlands Navy have been equipped with the update.
On the 25th of September 2017, as part of the exercise Formidable Shield 2017 the SMART-L MM radar system mounted on the test tower at the Thales premises in Hengelo, detected and tracked a ballistic missile launched from the Hebrides in Scotland at an average range of more than 1500km without difficulties.[citation needed] The Thales SMART-L Multi Mission radar in Hengelo detected the target as soon as it appeared over the horizon and maintained a stable track for more than 300 seconds. The track quality was sufficient to enable Launch On Remote by BMD-capable naval ships.
