Abstract :
The method of generalized eigenvector decomposition (GEVD) is proposed for extracting the poles of a radar target by using the autocorrelation of target late-time impulse responses in the paper. The additive noise in the signal is considered in the method. It can be used to evaluate the poles when only the amplitude data of multiple frequency returns is available. The simulation results in the paper illustrate that the new method has advantages over the generalized pencil of function (GFOF) method in the noise sensitivity and the computation.<>
