Abstract

A polynomial Wigner-Ville distribution (PWVD) of order six that necessitates a lower order of interpolation and which is more appropriate in the estimation of the intermediate frequency (IF) of a polynomial frequency modulated signal is proposed. The eighth-order PWVD is proposed for the analysis of a signal generated by an overflying aircraft as heard by a stationary observer. The superiority of the proposed eighth-order PWVD over lower order PWVD's was demonstrated.
