A vertically polarized radar antenna for remote sensing applications
Abstract
A vertically polarized radar antenna is designed which consists of one hundred waveguide radiating elements. The radiating elements are located linearly, side by side, forming a line source of one hundred wavelengths in length and mounted inside a sectoral horn to shape its vertical radiation pattern. The unit was designed to provide low side lobes (less than 30 dB) in the horizontal plane and a beamwidth around one degree. In the vertical plane the antenna pattern was required to have sidelobe levels less than 2 dB and a beamwidth in excess of fifteen degrees. The unit was designed to be used as a remote sensing radar for investigation of ice formations in northern waters.
