SAR imaging research of ship considering the effect of reflected waves from sea surface

In the imaging simulation of ship target, the influence of sea surface echo signals on the imaging cannot be ignored. In order to verify the influence of sea surface on the ship, this research uses the geometric optics and physical optics (GO-PO) method, and considers the characteristics of the echo signal. This allows for the calculation of bistatic scattering coefficients of ships alone and ships with the sea surface respectively. The CS algorithm is then used for imaging simulation, thus verify the influence of sea surface on imaging. The results show that the bistatic scattering contribution caused by reflected waves from the sea surface has a certain impact on the imaging of ship targets, but has little impact on the overall imaging simulation. It well verifies the effectiveness of the ship imaging algorithm, and provides the possibility for the realization of the target detection.
