Abstract : This application discusses an L-band radar and an antenna array operating with an existing X-band surveillance radar to provide a foliage penetration capability. The foliage penetration antenna consists of an array of L-band, stripline dipole/director elements placed in front of an array of broadwall waveguide slots which define an X-band aperture. The X-band aperture in addition to its own function, serves as a reflector for the diople/director elements. Aperture sharing is thus provided for a dual frequency antenna without increasing the size of the existing X-band aperture. (Author)
