Abstract

Abstract

The dual space theory is introduced for extracting the natural frequencies of a radar target from a measured response. The theory not only contains Prony method,SVD method and E pulse method, but also gives a new scheme-the Combination Operation(CO) method, which is shown to be more insensitive to random noise and to estimation of modal contents. Verification of the CO mehtod is accomplished by comparing the numerical results with those of the other three methods. The applicability of CO method to a conducting sphere is also demonstrated.
