Abstract :
In remote sensing problems for continuous inhomogeneous media, the Born approximation is used conveniently for tenuous, slowly changing media. The Rytov approximation is known, under certain circumstances, to give more accurate indication than the Born approximation, we have introduced an improvement that further increases the range of validity of the Rytov approximation. Some numerical results are presented to illustrate the advantages of the method introduced over that of Born and Rytov.
