the step frequency response equation of optical-region radar target is firstly established by using theories of multiple scattering centers and local resonance. In the equation
different approximate model is used to describe the local Rayleigh or resonant response of each scattering center. Then a novel method of target structure imaging based on band-limited response data for target spacial features extraction is presented. The obtained quasi-two-dimensional image provides target features of not only range response under wide-band waveform stimulation
such as one-dimensional range profile
but geometrical structure category of each local scattering center also. The features can be used for radar target identification.
