    • In a radar having electrical transmitting and receiving circuitry, and an antenna for the radiation of microwave signals, there is provided an optical feed system which couples the antenna with the transmitting and receiving circuitry. The feed system includes a set of optical multiplexers interconnected by sets of optical fibers. Microwave energy of the radar is converted to optical radiation for communication to the antenna, and then converted back to the microwave energy. Electro-optic modulators and photoelectric detectors provide for the energy conversion. A plurality of signals, including both signals having the transmit waveform as well as control signals, can be simultaneously coupled via the optical fibers by utilization of radiation of differing frequencies. The multiplexers include dichroic mirrors for separation of the radiations of the differing frequencies. The fiber optic feed system retains the full beam steering capacity of the radar and permits the use of conventional electronic circuitry with the feed network of the optical feed system.
    • 在具有电气发射和接收电路的雷达和用于辐射微波信号的天线中,提供了将天线与发射和接收电路耦合的光馈电系统。 馈送系统包括通过一组光纤互连的一组光复用器。 将雷达的微波能量转换成用于与天线通信的光辐射,然后转换回微波能量。 电光调制器和光电探测器提供能量转换。 包括具有发射波形的信号和控制信号的多个信号可以通过利用不同频率的辐射经由光纤同时耦合。 多路复用器包括用于分离不同频率的辐射的分色镜。 光纤馈送系统保留雷达的全波束转向能力,并允许使用常规电子电路与光馈电系统的馈电网络。
