Abstract

This paper examined the feasibility of performing bistatic Radar Cross Section (RCS) measurements in the Boris Vian anechoic chamber. To test this anechoic chamber, a small PEC circular cylinder is selected as a target. The capability to measure the bistatic RCS of a target versus frequency and versus target azimuth angle is established. Accurate bistatic RCS measurements are obtained using a Vector Network Analyzer and using background subtraction, bistatic calibration, and software range gating. A method to establish the chamber directivity is proposed. The accuracy of the measurement is estimated and a new value of the RCS sensibility is given as a function of the value of the chamber directivity.
