SMART-L (Signaal Multibeam Acquisition Radar for Tracking, L band)[1] is a long-range naval search radar introduced in 2002 by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal).

Design

[edit]

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.[1] Horizontal training is done by mechanically rotating the entire array.[citation needed]

As designed, SMART-L has a maximum range of 400 km (220 nmi) against patrol aircraft, and 65 km (35 nmi) against stealthy missiles.[2] A software upgrade, Extended Long Range (ELR) Mode, extends the maximum range for the detection of ballistic missiles to over 2000 km,[3] since 2018 all four Zeven Provincien class Frigates of the Royal Netherlands Navy have been equipped with the update.[4]

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 1500 km 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.[5]
