In civil and special application radar systems broadband radar technologies are widespread. Electrodynamic computer simulation is used for development of modern radar systems. It's important to study new effective ways of detailed radar image analysis for automatic radar identification. The conventional approach to a radar imaging and a data visualization is based on the Fourier transform method. This method has restrictions and it's hard to identify close scattering centers because of a

Radar length and intensity of scattering centers of a radar target are evaluated by MUSIC method. The main advantage is an ability to identify scattering centers within one resolution element (resel). In order to demonstrate the ability of the developed method broadband frequency characteristics of two typical radar targets are calculated. Intensity and relative distance of scattering center can be more over evaluated with a high accuracy. Stability testing of results to white noise is given.
