  • Device for two-dimensional imaging of scenes by microwave scanning
    Patent number: 8009116
    Abstract: For two-dimensional imaging of scenes through continuous passive or active microwave scanning, use is made of a fully mechanized directional antenna array comprising a main reflector (1), a primary radiator array (3) and a subreflector (2) having a small size in comparison to the main reflector and being tilted relative to the optical axis (7) of the directional antenna array. First drive means (8) are operative to rotate the subreflector (2) about the optical axis (7), and second drive means (17,18) are operative to move the total directional antenna array in a direction approximately vertical to the optical axis (7). The moving speed of the subreflector (2) is very high in comparison to that of the total directional antenna array.
