| Abstract: | In this paper we first present some essential properties for continue fractional Fourier transform and discrete fractional Fourier transform. Based on these properties we propose an analytic formula to reconstruct wave fields. This method can simplifies significantly the computational manipulations and improves the quality of reconstructed wave fields. Simulation experiments show that this method has good munerical stablity and higher computational accuracy. |
| Keywords: | Reconstruction wave field fractional Fourier transform analytic formula |
