Simulative calculating method and system for multi-path scattering characteristics of sea skimming target

The embodiment of the invention provides a simulative calculating method and system for multi-path scattering characteristics of a sea skimming target, and relates to the technical field of radar target characteristics. The method comprises the following steps: performing surface element treatment on a sea surface sample; calculating a surface element scattering rate of a local sea surface of a sea surface sample subjected to surface element treatment through a dual-scale method; separately calculating induction electromagnetic current, generated on the surface and the edge structure of a target object, of radar electromagnetic waves through a physical-optical method and an equivalent electromagnetic current method; combining self-scattering characteristics of the target and the sea surface through a mirror image method, and calculating multi-path coupling scattering of the target-sea surface. According to the simulative calculating method and system for multi-path scattering characteristics of the sea skimmi
