S1850M is a derivative of SMART-L
The Smart-L Volume Search Radar is a member of the advanced 3D multi-beam radar family, and is designed according to the NATO specifications for a Volume Search Radar. The solid state D-band (or L-Band), Smart-L provides undisturbed wide area awareness of a 400 km range up to 70 ' elevation. Full Doppler processing for instantaneous radial velocity measurement and clutter suppression, combined with refined signal processing, guarantees excellent performance, especially against stealth targets in a littoral environment.
Smart-L can be fitted with anti-ballistic missile defence capabilities. The S1850M Volume Search Radar is a Smart-L based radar with specific customer adaptations in co-operation with BAe.
The Smart-L / S1850M is the de facto standard of the major European navies for their long-range 3D radar requirements and foreseen as one of the pillars in the NATO TBMD.
