Geometric position Electromagnetic scattering Radar imaging Fig. 1 The scheme of EM scattering properties calculation

By Em Scattering


currents bounded by the object to generate field, subject to constraints imposed by boundary conditions. To determine the object’s scattering properties, we must visualize the object features which stimulate the scattered fields. A quantitative, spatial distribution of scattered fields is determined by the integrated effect of the current distribution. The latter cannot be measured directly by radar. Nevertheless, we strive to obtain, from measurements of scattered fields by a remote sensor, any information leading to the spatial separation of object features responsible for the scattering. That is what the imaging do[4,5]. In order to get the object’s scattering properties, three stages are: (1) 3-D model of objects generation, (2) the object’s scattering calculation, (3) production of the spatial distribution of scattering (Fig. 1)
