COMPACT RANGE REFLECTOR EDGE TREATMENT IMPACT ON ANTENNA AND SCATTERING MEASUREMENTS

Compact range measurements with a serrated edge and a blended, rolled edge reflector are compared in this paper, This is done by using simul ated antenna pattern and backscattered field measurements, The measure ment errors caused by stray signals emanating from the edge terminatio n of reflector are discussed, It has been found that different stray s ignal sources impact measurement accuracy from different aspect angles , In addition, the measurement accuracy achievable with different refl ector systems is dependent on the characteristics of the antenna or sc atterer under test, From these findings, one will be better able to un derstand how well these two types of reflectors will perform in terms of accurately providing the proposed measurements, Consequently, one w ill be able to choose the best reflector design for his/her applicatio n.
