A monopulse precision landing or other land-based radar system uses an array antenna and a beamformer to produce sum, azimuth difference and elevation difference beams relative to the array. The rows and columns of the array are skewed relative to the horizontal for tending to reduce the effects of multipath propagation on altitude estimates. A coordinate converter converts target information from the skewed antenna coordinates to ordinary vertical and horizontal coordinates.
