The Type 911 is dual frequency (X-Band and K-Band) differential tracking radar designed specifically to match the engagement envelope of the Seawolf missile. The Type 911 spots targets at low elevations, such as sea-skimming missiles, and in cluttered environments.
The X-Band tracking antenna is a Cassegrain reflector with monopulse feed. The reflector is fed by a wide angle four-horn monopulse cluster. This part of the radar is derived from the ST800 radar family.
