Abstract :
High-Resolution Wide-Swath (HRWS) Synthetic Aperture Radar (SAR) is a multi-static spaceborne Radar. The performance of the Radar system is improved by the mean of DBF on receive in azimuth and in elevation. This requires an relieve antenna array with large number of elements. In this paper the performance of large antenna array under the influence of plane distortions is analyzed. Presented is the influence on the array factor of symmetrical, unsymmetrical and random mechnical distortion. The paper considers also the influence on the performance of the antenna distortion on the High-Resolution Wide-Swath (HRWS) Synthetic Aperture Radar (SAR) in elevation.
