SMART-S Signaal Multibeam Acquisition Radar for Tracking, S band is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland,[1] formerly Hollandse Signaalapparaten (Signaal). SMART-S Mk2 is very successful. Only six years after its introduction, 30 systems were sold to navies all over the world. The radar transmitter/receiver (T/R) modules for the MK-2 are purchased by Thales from ASELSAN of Turkey.[2][3]

The system has two operating modes: medium range up to 150 km (81 nmi) at 27 RPM and long range up to 250 km (130 nmi) at 13.5 RPM.
