Scattering amplitude data for several objects:
The bounding box is (-1,-1) to (1,1) m, and the frequency is
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
