| Abstract: | The general mathematical model for moving targets is established by using polynomial expression. Polynomial Wigner Ville Distribution (PWVD) is introduced to analyze moving targets in time-frequency representation. The theoretical analysis and computer simulation show that PWVD can overcome the natural limitation of quadratic WVD in representing the moving targets and that it is practical. |
