| Abstract: | In this paper, using the component of the impulse response of target, a time-domain bispectrum estimating algorithm based on complex target is presented, this algorithm can estimate the scattering centers of target. The experimtental data of the compression airplane model according to proportion was analyzed in term of the above algorithm, using the impulse radar experimental system which is developed by the Team of Anti-Stealth Impulse Radar, Department of Electrical Engineering, National University of Defense Technology. The validity of the algorithm was shown by the experimental results. |
