A dynamic method for the measurement of forward scattering in a radio anechoic chamber is described. The quantity determined is the induced-field-ratio (IFR) of conducting cylinders. The determination of the IFR is highly sensitive to 1) multiple scattering between the cylinder and the obpring antenna and 2) extraneous scattering from the lining of the anechoic chamber. In order to eliminate the influence of multiple scattering, the measurements are made dynamically, i.e., the cylinders are mounted on a moving cart. The consequences of this movement are analyzed. Experimental data are presented in terms of the dynamic measurements. The influence of extraneous scattering is evaluated and an indication of a method for reducing errors due to extraneous scattering is given.
