MK-74鞑靼防火控制系统已不断升级以满足当前的威胁,MOD 14/15系统部署CGN-36,-37,-40,-41和DDG-993级船舶。MK-74目标跟踪照明系统支持标准导弹-2(SM-2)指导到SM-2的最大范围。集成的X波段连续波照明(CWI)功能支持SM-2的终端照明,后部参考和上行链路要求。MK74部署在许多船舶类型和世界各地的配置上。MOD 15通过新的5通道接收器,接收器天线和高级信号处理器添加X波段连续波采集和轨道(CWAT)功能。
GMFC由三个主要设备组和相关辅助组件组成:雷达发射器组,连续波照明器集团,导演组和辅助设备。雷达发射器组包括接收器 - 发射器单元,其产生,放大和发送RF能量以进行目标获取和跟踪。接收器 - 发射器接受所有信号返回并且是频率敏捷。天线组件形成用于跟踪的Monopulse光束,用于反射照明的导弹归巢的铅笔束,以及用于导弹后部参考和上行链路通信的形状的广角梁。ECM喇叭安装在天线上,以提供电子对策信息。雷达集控制台为操作员监控的战术操作和测试功能提供了显示和控件。发射器组的雷达数据处理器部分是中央控制处理器。此外,处理器接受指定和参与控制订单,将导演定位并执行数据提取。GMFC具有驻留在雷达数据处理器中的操作软件程序,可控制灭火系统的大部分操作。连续波照明器组传输RF以照亮标准导弹的目标。 To support the transmission of coded uplink messages to in-flight STANDARD missiles, the CWI transmitter provides frequency shift modulation of the signal. The director group positions the radar antenna in reponse to radar data processor orders. Director train is unlimited with elevation limited between -30 degrees and +83 degrees in the vertical. The auxiliary group provides a computer display terminal that includes a CRT display and a data entry keyboard for operator communication with the radar data processor. Information such as analog, logical, and digital data, equipment status, radar performance and test results can be displayed on the CRT. A hardcopy unit provides a printed copy of the CRT display. The auxiliary group also includes a CWI test set for determining signal validity.
