SMART-L (Signaal Multibeam Acquisition Radar for Tracking, L band)〔(【引用サイトリンク】title=SMART-L Radar )〕 is a naval long-range search radar from Thales Nederland, formerly Hollandse Signaalapparaten (Signaal). The passive electronically scanned 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.〔 Horizontal training is done by mechanically rotating the entire array. As designed, SMART-L has a maximum range of against patrol aircraft, and against stealthy missiles.〔(【引用サイトリンク】title=SMART-L 3D Long range surveillance radar )〕 A software upgrade, Extended Long Range (ELR) Mode, extends the maximum range to . In 2006 HNLMS ''Tromp'' used the ELR Mode to track an ARAV-B missile from during a US Navy ballistic missile defence exercise. ==Variants== * SMART-L * SMART-L Early Warning Capability (EWC) * SMART-L EWC Ground Based (GB) * S1850M 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SMART-L」の詳細全文を読む スポンサード リンク
