Abstract

To enhance the dynamic range of monostatic RCS measurement in compact anechoic chamber, this paper presents the quantitative evaluation of simple CW measurement method by using transmitting and receiving antennas. The mutual coupling is reduced by several approaches such as the separation between antennas, suppressing the sidelobe level, and inserting the shielded conductor. The measurable maximum and minimum RCS values are clarified. The effect of the arrangement of wave absorber in target side is also shown.
