Scattering strength weighting method used for imaging of ground penetrating radar

The invention discloses a scattering strength weighting method used for the imaging of a ground penetrating radar. The scattering strength weighting method comprises the following steps of: 1. extracting scattering data: extracting the scattering data of a time delay curve corresponding to a certain mesh (zm, xn) in an imaging area, that is to say, wm, n=[qm, n, 1, L, qm, n, L]; and 2. obtaining the imaging result on the basis of a weighting factor: traversing all the meshes in the imaging area, and respectively calculating the weighting factor Alpha (zm, xn) of each mesh and the sum of scattering data of the time delay curves corresponding to all the meshes so as to obtain the imaging result of the whole imaging area, wherein m equals to 1, L, L, z; and n equals to 1, L, Lx. The scattering strength weighting method used for the imaging of the ground penetrating radar can be used for improving the imaging quality of the ground penetrating radar.
