13.1 Finding the position and size of a small body from the scattering data.

Consider a system of two bodies one of which D1, is large compared with the wavelength and the other one, D2, is small. Let a denote the characteristic size of the small body.

Then ka image 1, where k is the wave number. In applications one may think that D1 is a ship and D2 is a mine.

Let us assume that the body ...
