## Scattering amplitude data for several objects:

The bounding box is (-1,-1) to (1,1) m, and the frequency is
300 MHz.
- scat1_sa.dat
- scat2_sa.dat
- scat3_sa.dat
- scat4_sa.dat

The file format is:

Incident angle (degrees), Scattered angle, Real
part of scattering amplitude, Imaginary part

(exp(j omega t) time convention)
To load the files, use

sa = load('scat1_sa.dat');

F = sa(:,3)+j*sa(:,4);

NA = sqrt(length(F));

F = reshape(F,NA,NA); % incident angles along columns, scattered
angles along rows
