AbstractIn this work a novel scaltering center extraction method using genetic algorithm based CLEAN is proposed. Initial values for optimization parameters are estimated from the power spectra of the measured data using Fourier transform.The proposed method reduces computational time compared to existing evolutionary programming (EP) based approaches.
