Bistatic radar cross-section measurements by pendulum method

In this paper, the pendulum method for measuring the bistatic radar cross section of a target is proposed, based on the principle of modulated-scattering technique. A modulated wave is formed by swinging the target like a pendulum. This method has the advantages that the measuring procedure is very simple, an absorber-coated room is not required, and the measured value is independent of background waves. Theoretical aspects of the principle are first described, including various kinds of conditions; then the measuring method is given with experimental results.
