SMART-L
SMART-L (Signaal Multibeam Acquisition Radar for Tracking, Lband)[1] is a naval long-range search radar from Thales Nederland, formerly Hollandse Signaalapparaten (Signaal).
The phased array antenna 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.
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 to 480 km (260 nmi). In 2006 HNLMS Tromp used the ELR Mode to track a ARAV-B missile from 150 km (81 nmi) during a US Navy ballistic missile defence exercise.[3]
