ABSTRACT:
A height finding arrangement for a range/azimuth surveillance radar using a mechanically rotated planar antenna array. The received outputs from the array are combined with suitable weighting functions to give two sectorial pattern signals whose effective phase centers are respectively above and below the center of the array aperture. The phase difference between these two signals is measured to provide the elevation angle of the target.
