An Investigation of Bistatic Calibration Objects
Several popular metallic bistatic calibration objects
are investigated, including a sphere, long and short cylinders,
dihedral, trihedral, circular disk and wire mesh. Comparisons
are made between the advantages and disadvantages of various
objects for calibration. The analysis addresses sensitivity to object
alignment error, availability of accurate radar cross section (RCS)
calculations and bistatic RCS levels. Both theoretical concepts and
practical considerations are discussed based on measurements
accomplished at the European Microwave Signature Laboratory
(EMSL) of the EC Joint Research Center (JRC) in Ispra, Italy.
This facility has the capability to produce far-field fully polarimetric
precision bistatic measurements in a 30 cm diameter quiet
zone, suitable for comparing different calibration objects.
