Abstract
The microwave image of a metallic object is interpreted
from a new point of view, based on the understanding of the interconnection
between the scattering mechanisms, the data acquisition system,
and the image reconstruction algorithm. From this understanding
we are able to interpret and predict microwave images reconstructed
from data collected over specified and angular windows. The connection
between a special scattering mechanism, edge diffraction, and its
reconstructed image is established. The microwave image of an edge
will he two bright points whose locations correspond to the end points
of the edge if the normal aspect angle is not included in the angular
windows; otherwise a line joining the two end points and representing
the edge will appear in the image. Experimental images of a trihedral
reflector reconstructed from data collected over different angular windows
support this new approach to image interpretation and prediction.
