Abstract:

A new method for coherence enhancement is proposed based on the mathematical model on the relationship between the amplitude and the phase of the complex signals. An optimal projection direction of scattering vectors is derived for maximizing the amplitudes of the master and slave complex images. The experimental results demonstrate the effectiveness of the proposed approach.
