Abstract :
A technique to extract the resonant frequencies of a radar target is presented. The scheme is completely automated, with only the number of natural modes expected and the beginning of late-time as inputs. Results using experimental data demonstrate the insensitivity of the method to random noise and to estimates of model content. The technique is computationally efficient, taking only a few minutes to execute on a personal computer
