    摘要: A reflector antenna arrangement can transmit and receive both infrared (IR) and millimeter wave (RF) radiation. The arrangement includes a main reflector (1), a subreflector (2), an IR feed system (4), an RF feed system (3), a radome (5), and a bispectral window (6) arranged in an opening provided in a central area of the main reflector (1). The RF feed system is oriented so that the RF radiation path includes a double reflection from the subreflector and from the main reflector, while the IR feed system is arranged directly behind the bispectral window so that the IR beam path extends directly through the bispectral window without reflecting from the main reflector or the subreflector. The bispectral window has a high reflectance for the RF radiation and a high transmittance of the IR radiation. The bispectral window is made of a dielectric material and has rotationally symmetrical front and back surfaces, whereby the front surface contour is optimally matched to the front surface of the main reflector and the back surface contour achieves an optimal reflectivity of the RF radiation and an optimal transmissivity of the IR radiation. Undesired influences between the IR radiation and the RF radiation are avoided by the separation of the signal beam paths.

    摘要: A double reflector antenna mounted on a terrestrial mount with Azimuth and elevation shafts in which a primary field radiating and detecting horn is mounted within a housing behind a central opening of the main reflector dish so as to radiate and receive energy from a sub-reflector mounted at the focal point of the main reflector dish and such that the lead supplying energy to and from the horn can be very short and the horn can be substantially shielded from snow and rain.
