For the optical system with circular apertures,it is difficult to get the boundary radical slope of phase and the accurate sampling value in the circular domain boundary when the intensity transport equation is used to recover the original phase.

And mutual coherence function propagation equation(MCFPE) is also raised into MMW-SAR near sensing imaging,which can eliminate the fuzzy problem of imaging through twice Fourier transform and improve the imaging quality.

Objective quality assessment to image restoration based on traveling wave equation -- An experimental verification;

First it uses the double line interposition and the minimum summation of grey value in differential coefficient image to extract the direction of motion blurred image,then uses traveling wave equation to restore the blurred image which is caused by uniform linear motion.

Transmission matrix solution of seismic propagation equation in viscoelastic layered and porous media;
