A new fast 2-D superresolution imaging algorithm
A novel method is proposed for reconstructing the 2-D scattering centres of radar target,research the frequency scatter model of electromagnetic scattering,we resolve the problem by extracting two 1-D scattering centres parameter instead of extracting directly 2-D scattering centres parameter,separately estimate the 1-D scattering centres in range dimension and cross dimension using conjugate unitary Root-MUSIC algorithm,group them and attain all possible spatial frequency pairs,then the unveracious frequency pairs are eliminated by spatial filtering,achieve the 2-D scattering centres parameter.
