DBRI 23

DBRI 23 is operating in L-Band 3D air- and surface surveillance and target designation radar, designed for the French Masurca surface-to-air missiles.

The transmitter uses a carcinotron with an output power of several megawatts. The antenna is protected by a large radome. It provides an inverse cosecant squared antenna pattern by using of an array of feed horns. Elevation angle information is obtained by the use of stacked beam techniques.

DRBI-23 is installed aboard the French Navy's air defense destroyers D 602 FS Suffren and D 603 FS Duquesne.
