%X SAR/ISAR image processing involves a 2D Fourier transform that produce high intensity sidelobes which obscure low intensity scatters in the image. Although sidelobes can be reduced using parametric windows, the image resolution becomes worse. Apodization technique can reduce sidelobe levels while maintaining the image resolution. In this paper, based on the analysis of apodization algorithm, a modified apodization method is presented via stronger constraint. The modified method has higher resolution and lower sidelobe levels than the original method. The correctness of this method is proved by using a real ISAR image.
