This research examined the applicability of the monostatic-bistatic equivalence theorem MBET and associated extensions in determining the extent to which correlation exists between monostatic and bistatic data for both the near and far-field. A secondary objective was to determine whether reliable bistatic near-field radar cross section RCS data could be collected on a range originally designed to take monostatic far-field measurements. Dr. David Falconer developed two extensions of the MBET in an effort to estimate the bistatic RCS pattern in both the near and far-field by measuring the monostatic RCS pattern at one-half the bistatic angle, at a reduced frequency, and, for the near-field case, at an adjusted target-to-receiver separation range. The pattern representation and accuracy of these two extensions were examined by measuring the RCS of an ogive, a circular flat plate, and two circular cylinders of different lengths. Theses.
