Abstract

Several popular bistatic calibration techniques are evaluated, and comparisons are made between the relative merits of various calibration objects. This analysis considers the following: sensitivity to object alignment error, sensitivity to polarization impurity, and ease of implementation. Both theoretical concepts and practical considerations are discussed, based on measurements accomplished at the European Microwave Signature Laboratory (EMSL) of the Joint Research Centre (JRC) in Ispra, Italy. This facility has the capability to produce far-field, fully polarimetric, bistatic measurements with an approximately 30 cm diameter quiet zone, with the necessary precision for comparing different calibration methods
