S 1810

S 1810 is operating in the X-Band pulse-to-pulse frequency-agile radar which is optimized for shipborne applications. The radar using the standard antenna is named S 1810 A, with the reflectors wide of 2.4 m. The compact version with an antenna of 1.2 m (beam width: 2.2°) is named S 1810 C. The shipborne antennas are mounted on a fully stabilized platform. The version for coastal defense got the name suffix S 1810 (CD).

The radars can be combined with an operating in D-Band secondary radar whose dipoles are fitted to the bottom edge of the primary antenna reflector.

The radars are optimized for the detection of surface targets and low-altitude aircraft in heavy ECM environments. They use intrapulse modulation with a pulse compression rate of 20:1 in the long pulse. The own ship movement can be compensated in the moving target detection and sea state suppression.
