Computation of radar cross section in high frequency region for SAR imaging simulation of ship targets
用于舰船目标SAR成像仿真的高频区RCS计算

To compute Radar Cross Section (RCS) in high frequency region, a method that combined with fast modeling and improved graphic electromagnetic computing was presented. Using the collecting information of ship and the modeling software, the figure of the ship was modeled accurately, the radar cross section was computed exactly by improved graphic electromagnetic computing algorithms integrated Physical Optics (PO) method and Incremental Length Diffraction Coefficients (ILDC) method, simulation experiment shows that it can get a good simulation result of SAR images by this nearly real-time method.
