Electromagnetic scattering of ground surface combining with man-made target: Modeling and simulation

Abstract

In order to obtain the electromagnetic scattering of ground surface combining with man-made target. The geometric composite pyramid-ground model is built by the means of digital elevation data superposition method and the faceted element is used to describe the composite model to calculate the electromagnetic scattering. Then the echoes of the composite model are obtained by superimposing the echoes of all the facets. The simulation results show that the feature similarity between the geometric model and the simulation image is consistent. In addition, the fluctuation of the corresponding ground coordinate is also consistent.
