A modification of ultra wideband aspect independent radar target discrimination method using fourth-order cumulant preprocessing is introduced. It based on the natural frequencies of the objects. The increasing of the accuracy of parameter estimation can be achieved if the correct choice of one-dimensional slice of 3-D fourth-order cumulant sequence is made. The usage of this technique with signature algorithm leads to the increasing of the true discrimination probability if the space of attributes includes the most informative parameters of the objects. The results of experimental research of the signals scattered by the scaled aircraft models by using the signature algorithm with fourth-order cumulant preprocessing are presented.
