The layover and shadow phenomenon is serious in urban areas, where the interferometric phase is complex and disordered and interpretation of an image is difficult. Therefore, it is always a hot and difficult problem for InSAR processing. SAR image si

Complex motion can cause serious defocusing phenomena in high resolution spaceborne SAR cases, which then lead to decreased image resolution. In this study, we built a simulation model to quantitatively analyze the signature and effect on maritime fl
