Abstract :
In SAR imagery, strong returns from a group of man-made reflectors obscure adjacent target areas leading to a significant loss of information. The wide dynamic range of response levels from urban area is the source to degrade the SAR image characteristic. In this paper, we explore a way to interpret this problem in SAR imaging and propose a waveform design technique to improve target detection performance
