  • Electronically scanned hemispheric antenna
    Publication number: 20080106482
    Abstract: A low-profile, electronically scanned antenna that can scan a hemisphere is comprised of three, phased array radiators. Each radiator face has an azimuth and elevation scan angle equal to 120 degrees. The three radiator faces are arranged in a truncated 3 sided pyramid such that they prove continuous hemispherical coverage. The three radiators are mounted to cooled panels of a truncated pyramid-shaped frame such that the radiators enable a full hemisphere to be scanned by radar.
