Embodiment Construction
[0081] Below in conjunction with accompanying drawing of description, the present invention will be further described.
[0082] The present invention provides a method for correcting a through-wall radar datum plane based on reverse time inversion, comprising the following steps:
[0083] 1) Establish a through-wall imaging model;
[0084] Such as figure 1 As shown in , it is assumed that the target to be searched is placed between two layers of walls, and the two layers of walls are the front wall and the back wall in turn; figure 1 As shown in , the targets are square electrical conductors, which are target 1, target 2 and target 3 respectively; the front wall and the rear wall are uniform dielectric plates, the thickness of the uniform dielectric plate is d, and the relative permittivity is ε r , the conductivity is σ, and the specific parameter values of the homogeneous dielectric plate are input into the simulation system according to the requirements of the model for...
