Two-Dipole Model Based Coherent Radar Target Decomposition

A method for recovering objects parameters by experimental data based on the two-dipole model of target representing is discussed in the paper. The goal of the investigation is to develop the method of remote sensing objects parameters definition by measured data. A considered method is built on analysis of analytic expressions of PSM elements for a two-dipole mathematical model of object representation. The proposed method was applied to recover the parameters of different objects for which complex PSM’s were experimentally obtained. Some objects signatures were obtained and considered based on recovered parameters and provided their statistical analysis. Obtained results indicate the adequacy of the two-dipole model and appliance for modelling the real objects prototypes to study the process of transforming electromagnetic waves at reflecting from object also a possibility of radar targets imitating. Obtained results can be useful in solving radar objects recognition and classification problems.
