# Wigner distribution reconstruction from two projections

## Tatiana Alieva, Martin J. Bastiaans, and LJubisa Stankovic

The connection between the instantaneous frequency and the angle derivative of the fractional power spectra is established. It permits to solve the signal retrieval problem if only two close fractional power spectra are known. This fact is used in the reconstruction of the Wigner distribution or the pseudo Wigner distribution from two close projections.
