in fig1 such an imaging system is described in u s pat no 6 965 340 entitled u201c system and method for security inspection using microwave imaging u201d incorporated herein by reference in operation source receive antenna 100 illuminates programmable array panel 110 processor 150 controls the individual elements of programmable array panel 110 and micro waves from source receive antenna 100 to scan a particular voxel in three dimensional space in particular subject 200 while shown in fig1 as coincident source and receive antennas may be separate if as shown in fig 1 subject 200 is opaque the image produced as 300 does not reveal a true indication of subject 200 according to the present invention and as shown in fig2 reflective surface 120 is placed within the scan range of source receive antenna 100 and programmable array panel 110 now the resulting image may be analyzed by processor 150 using not only microwaves reflected by subject 200 as in normal mode operation but also including the additional silhouette information provided by reflective surface 120 as shown in image 310 of fig2 subject 200 produces a clear silhouette in one embodiment of the present invention imaging data is effectively combined by displaying the maximal.
