Abstract: With bispectrum analysis, an AR model parametric bispectrum estimation is presented for radar target echoes. A detail analysis of actual aircraft echoes and a reasonable selection of target signature are made, with a formation of signature vector for target identification. The experimental results show that the method is feasible and effective. -
