SAR IMAGE SIMULATION OF SHIP TARGETS BASED ON MULTI-PATH SCATTERING
Synthetic Aperture Radar(SAR)plays an important role in the classification and recognition of ship targets because of its all-weather working ability and fine resolution.In SAR images,besides the sea clutter,the influence of the sea surface on the radar echo is also known as the so-called multipath effect.These multipath effects will generate some extra pseudo images,which may cause the distortion of the target image and affect the estimation of the characteristic parameters.In this paper,the multipath effect of rough sea surface and its influence on the estimation of ship characteristic parameters are studied.The imaging of the first and the secondary reflection of sea surface is presented.The artifacts not only overlap with the image of the target itself,but may also appear in the sea near the target area.It is difficult to distinguish them,and this artifact has an effect on the length and width of the ship.
