SBR and PO technology-based strong scattering center calculation method

The invention belongs to the signal characteristic control technical field and relates to an SBR and PO technology-based strong scattering center calculation method. The calculation method comprises the following steps that: hotspot calculation is performed through ray tracing and physical optics; a distribution diagram which can indicate the radar cross section (RCS) contribution of each surface element of a target surface is obtained; and strong scattering parts can be located through comparing hotspot diagrams. Compared with a low-frequency method, and according to the SBR and PO technology-based strong scattering center calculation method, SBR and PO methods are adopted to calculate target hotspots, and therefore, high efficiency can be realized; hotspot contribution is attached to the surface of a 3D model, and therefore, the strong scattering contribution parts can be analyzed intuitively. The SBR and PO technology-based strong scattering center calculation method of the invention can trace separated two-times and three-times strong coupling structures. Strong multiple-times scattering which is generated through the coupling of separated parts on a target is usually difficult to discover, while, hidden strong scattering structures can be found out through the hotspot diagrams.
