Abstract
A method of calibrating airborne radar arrays using scattering from the surface of the earth is proposed. The method uses the mapping of clutter azimuth and elevation to Doppler frequency to separate the energy that is arriving from different azimuths and elevations. Calibration is then accomplished using the clutter data. Range and Doppler ambiguities are examined to predict the adverse impact these will have on the resulting calibration. The necessarily limited data collection time duration limits the resolution of the clutter scattering to some angular extent: the impact of this resolution on the calibration results are also examined.
