Abstract :
By using adaptive subarrays for crossrange imaging we have developed a computationally simple method that removes any image degradation caused by strong, discrete clutter located in the crossrange sidelobes of a synthetic aperture radar (SAR) image. The procedure is based on the minimization of the mean interference power with the constraint that the image of a desired scatterer is undistorted. The applicability of the approach has been illustrated by simulation
