It is of great significance to study the radar cross section (RCS) calculation and radar echo simulation technology of the electrically complex target.A simulation software is designed based on physical optics (PO) and shooting bouncing ray method (SBR) to comprehensively consider the effects of sea clutter and noise,and calculate dynamic RCS and radar echoes of ship.The RCS values are calculated for three ship models with different shapes and sizes,and the radar echo signals of these ship models in different scenarios are simulated and analyzed.The simulation results show that the dynamic RCS...
