Abstract:

A new effective 3D imaging algorithm, GRTCLEAN algorithm, for highspeed spinning targets is proposed. First, translational motion compensation for a highspeed target signal is made to translate it into turntable one.Then based on the feature of varying curves of spinning scatterers’profiles, the generalized Radon transformation (GRT) is used to obtain space position estimate of target scatterers. Finally, the target parameter estimation method is combined with modified CLEAN technology to obtain feature estimation of each scatterer, thus a 3D target image can be obtained. Theoretical derivation and simulation results verify the effectualness of this algorithm.
